CMake: Improve config installation

Use 'GNUInstallDirs' standard module to set destinations of installed
files.

Use uppercase "CURL" names instead of lowercase "curl" to match standard
'FindCURL.cmake' CMake module:
* https://cmake.org/cmake/help/latest/module/FindCURL.html

Meaning:
* Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
* User should call 'find_package(CURL)' instead of 'find_package(curl)'

Use 'configure_package_config_file' function to generate
'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
file smaller and handle components better. E.g. current configuration
report no error if user specified unknown components (note: new
configuration expects no components, report error if user will try to
specify any).

cmake: Backport to work with CMake 3.0 again

Changes in commit 7867aaa9a0 (cmake: link curl to the OpenSSL targets
instead of lib absolute paths, 2018-07-17) and commit f826b4ce98 (cmake:
bumped minimum version to 3.4, 2018-07-19) required CMake 3.4 to fix
issue #2746. This broke support for users on older versions of CMake
even if they just want to build curl and do not care whether transitive
dependencies work.

Backport the logic to work with CMake 3.0 again by implementing the
fix only when the version of CMake is at least 3.4.

openssl: assume engine support in 1.0.1 or later

Previously it was checked for in configure/cmake, but that would then
leave other build systems built without engine support.

While engine support probably existed prior to 1.0.1, I decided to play
safe. If someone experience a problem with this, we can widen the
version check.

curl.rc: embed manifest for correct Windows version detection

* enable it in `src/Makefile.m32`
* enable it in `winbuild/MakefileBuild.vc` if a custom manifest is
_not_ enabled via the existing `EMBED_MANIFEST` option
* enable it for all Windows CMake builds (also disable the built-in
minimal manifest, added by CMake by default.)

For other build systems, add the `-DCURL_EMBED_MANIFEST` option to
the list of RC (Resource Compiler) flags to enable the manifest
included in `src/curl.rc`. This may require to disable whatever
automatic or other means in which way another manifest is added to
`curl.exe`.

Notice that Borland C doesn't support this method due to a
long-pending resource compiler bug. Watcom C may also not handle
it correctly when the `-zm` `wrc` option is used (this option may
be unnecessary though) and regardless of options in certain earlier
revisions of the 2.0 beta version.
