tidy-up: delete parallel/unused feature flags

Detecting headers and lib separately makes sense when headers come in
variations or with extra ones, but this wasn't the case here. These were
duplicate/parallel macros that we had to keep in sync with each other
for a working build. This patch leaves a single macro for each of these
dependencies:

- Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`.

Also delete CMake logic making sure these two were in sync, along with
a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.

Also delete stray `HAVE_ZLIB` defines.

There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch
retains it for compatibility and deprecates it.

- Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.

Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from
`winbuild/MakefileBuild.vc`, these have a role when building libssh2
itself. And `CURL_USE_LIBSSH`, which had no use at all.

Also delete stray `HAVE_LIBSSH2` defines.

- Rely on `USE_LIBSSH`, delete parallel `HAVE_LIBSSH_LIBSSH_H`.

Also delete `LIBSSH_WIN32`, `LIBSSH_LIBRARY` and `HAVE_LIBSSH` from
`winbuild/MakefileBuild.vc`, these were the result of copy-pasting the
libssh2 line, and were not having any use.

- Delete unused `HAVE_LIBPSL_H` and `HAVE_LIBPSL`.

gnutls: Fix nettle discovery

Commit e06fa7462ac258c removed support for libgcrypt leaving only
support for nettle which has been the default crypto library in
GnuTLS for a long time. There were however a few conditionals on
USE_GNUTLS_NETTLE which cause compilation errors in the metalink
code (as it used the gcrypt fallback instead as a result). See the
below autobuild for an example of the error:

https://curl.se/dev/log.cgi?id=20210225123226-30704#prob1

This removes all uses of USE_GNUTLS_NETTLE and also removes the
gcrypt support from the metalink code while at it.

VMS: fix and generate the VMS build config

config_h.com is a new file that generates a config.h file based on the
curl_config.h.in file and a quick scan of the configure script. This is
actually a generic procedure that is shared with other VMS packages.

The existing pre-built config-vms.h had over 100 entries that were not
correct and in some cases conflicted with the build options available in
the build_vms.com.

generate_config_vms_h_curl.com is a helper procedure to the
config_h.com. It covers the cases that the generic config_h.com is not
able to figure out, and accepts input from the build_vms.com procedure.

build_curlbuild_h.com is a new file to generate the curlbuild.h file
that Curl is now using when it is using a curl_config.h file.

post-config-vms.h is a new file that is needed to provide VMS specific
definitions, and most of them need to be set before the system header
files are included.

The VMS build procedure is fixed:

1. Fixed to link in the correct HP ssl library.
2. Fixed to detect if HP Kerberos is installed.
3. Fixed to detect if HP LDAP is installed.
4. Fixed to detect if gnv$libzshr is installed.
5. Simplified the input parameter parsing to not use a loop.
6. Warn that 64 bit pointer option support is not complete
in comments.
7. Default to IEEE floating if platform supports it so
resulting libcurl will be compatible with other
open source projects on VMS.
8. Default to LARGEFILE if platform supports it.
9. Default to enable SSL, LDAP, Kerberos, libz
if the libraries are present.
10. Build with exact case global symbols for libcurl.
11. Generate linker option file needed.
12. Compiler list option only commonly needed items.
13. fulllist option for those who really want it.
14. Create debug symbol file on Alpha, IA64.
