build: add pytest targets

It enables running pytests in cmake jobs, regardless of underlying build
tool choice (= makes it work with ninja.)

Also:

- drop pytest logic launching `make` and exiting in case of failure.
Maybe there is a better way and keep this functionality somehow, bind
it to a command-line option? make it fail softly?

- GHA/linux: invoke pytest via the build, not directly.

- autotools: add missing dummy runtests targets when cross-compiling.

cmake: make `test-ci` target skip building dependencies

Make `test-ci` not depend on the `testdeps` target.

`test-ci` is designed to run curl tests in CI. In CI we build all
necessary dependencies explicitly beforehand, and they are always ready
when calling the `test-ci` step. Thus, it isn't necessary to enforce
them via a dependency rule. Dropping it saves redundant work and delay
in CI jobs.

The `testdeps` dependency should not normally be a problem. It's
supposed to be a no-op if those targets are already built. In practice
however, it causes a delay and/or an actual rebuild of those
dependencies depending on generator (= build tool) used and other
factors.

As observed in the GHA/windows workflow, the `testdeps` dependency:

- with Ninja, causes no delay, and no extra work:
https://github.com/curl/curl/actions/runs/10980099984/job/30485440389#step:25:18

- with GNU Make, caused a re-evaluation of `testdeps` targets,
but did not actually rebuild them. This re-evaluation took a
noticeable time (esp. with non-bundled tests):
https://github.com/curl/curl/actions/runs/10980099984/job/30485440155#step:14:11 (with bundles)
https://github.com/curl/curl/actions/runs/10973851013/job/30471690331#step:14:11 (w/o bundles)
verbose: https://github.com/curl/curl/actions/runs/10980506956/job/30486434629#step:14:13

- with MSBuild, caused a re-evaluation of `testdeps` targets, and
triggered a _rebuild_:
https://github.com/curl/curl/actions/runs/10980099984/job/30485435968#step:14:19 (with bundles)
https://github.com/curl/curl/actions/runs/10973851013/job/30471689714#step:14:19 (w/o bundles)
verbose: https://github.com/curl/curl/actions/runs/10980506956/job/30486436368#step:14:48
It's suspected that our use of
`-DCMAKE_VS_GLOBALS=TrackFileAccess=false` in CI is contributing to
this. This option is supposed to affect incremental builds only. For
some reason it affects CI builds too, even though they are not
incremental, and no sources are changed between build steps.
Reported-by: Aki Sakurai
Ref: #14999

Notice that `test-*` targets depending on `testdeps` is NOT sufficient
to build everything to run tests, e.g. it misses to build the curl tool,
which is essential. This is also true for autotools' `test-ci` target
which misses to build libcurl and the curl tool.

Perhaps it'd be best to drop `testdeps` as a dependency for _all_
`test-*` targets and make it official to require building dependencies
manually. Alternatively these targets could be fixed to rebuild
everything necessary to run tests.

tests: speed up builds with single-binary test bundles

Add support for single-block binaries that contain all libtests and
unit tests respectively.

Enable with:
- autotools: `--enable-test-bundles`
- cmake: `-DCURL_TEST_BUNDLES=ON`

(They are compatible with `--enable-unity` and `-DCMAKE_UNITY_BUILD=ON`
options, for further speed-up.)

Makes libtests and unit tests build _fast_, needing little disk space
even in static mode. Similar to CMake unity mode, but with a custom
script, also supporting autotools builds.

The price is having to deal with symbols/macros colliding between
`lib*.c` and `unit*.c` sources. Maybe with naming conventions or other
solutions this can be improved gradually and reduce the need for manual
intervention by `mk-bundle.mk`. I've included a script that does the bulk
of detecting name collisions.

- CI: build tests in more jobs.

cmake: allow building tests in unity mode

Makes building tests noticeably faster.

Apply changes/fixes/workarounds to make Unity work:

combined into single units.
- add workaround to avoid applying `lib/memdebug.h` overrides to system
headers declaring/defining `getaddrinfo()`/`freeaddrinfo()` for
`tests/server/resolve.c`. This replaces a previous workaround that
worked for that specific source.
- rename test macro `CTRL` clashing with Cygwin `sys/ioctl.h`.

CI: enable parallel testing in CI builds

The test-ci target now uses 2 processes by default, but the amount of
parallelism is tuned for each CI service and build environment based on
results of a number of test runs. Some CI services use super-
oversubscribed build machines that can barely run the curl tests
already with no parallelism without frequently failing with
timing-induced failures. These continue to be run without parallelism.
Other services provide two fast, unloaded cores and these run with 14
processes, which is a good default for this kind of environment.

Here's a summary of the number of test processes by CI service:

Appveyor - 2 (Windows MSVC), 1 (others)
Azure - 2
Circle CI - 14
Cirrus - 28 (macOS), 14 (Linux), 7 (FreeBSD), 5 (macOS torture), 2 (Windows)
GitHub Actions - 3 (macOS), 2 (Linux)

Some of these are a bit conservative to keep timing-induced flakiness down.

The net result is that the first test results should arrive only
3 minutes after a commit submission.

cmake: create `configurehelp.pm` like autotools does

Besides Apple, it also supports any gcc and clang builds, and MSVC.
For other platforms, it defaults to `cpp` (like autotools).

CI: ignore the "flaky" and "timing-dependent" test results in CMake

This was already done for automake builds but CMake builds were missed.
Test 1086 actually causes the test harness to crash with:

Warning: unable to close filehandle DWRITE properly: Broken pipe at C:/projects/curl/tests/ftpserver.pl line 527

Rather than fix it now, this change leaves test 1086 entirely skipped on
those builds that show this problem.

cmake: add support for "unity" builds

per target as a single C source. This is experimental.

cmake: add support for "unity" builds

Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.

You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.

It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.

Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.

Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
`statename`.
- rename `ssl_backend_data` structure to unique names for each
TLS-backend, along with the `ssl_connect_data` struct member
referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
builds when compiling `lib/ldap.c`. To support "unity" builds, we had
to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
`schannel.h` option) _globally_. This caused an indirect inclusion of
Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
as well. This requires `[P]UNICODE_STRING` types, which is apperantly
not defined automatically (as seen with both MSVS and mingw-w64).
This patch includes `<subauth.h>` to fix it.

- tweak unity builds to compile `lib/memdebug.c` separately in memory
trace builds to avoid PP confusion.
- force-disable unity for test programs.
- do not compile and link libcurl sources to libtests _twice_ when libcurl
is built in static mode.

KNOWN ISSUES:
- running tests with unity builds may fail in cases.
- some build configurations/env may not compile in unity mode. E.g.:
