Needed for subsequent change that will check and error out if the
version is lower than 3.16. We do that to ensure all policies
introduced by CMake up to version 3.16 have their behavior set to
NEW.

target_link_options are placed by CMake at the beginning of a linker
line. This gives us an opportunity to use the function to propagate
object libraries. This change adds one more check in the root
Config.cmake file. If CMP0099 policy is enabled, CMake enables
propagating of the linking options when linking two static libraries
using the PRIVATE linking visibility, so we can rely on the correct
linking order and expect object libraries to be propagated.
Note that on the platforms where cmake version is higher than 3.16
Qt uses CMP0099 NEW in functions like qt_add_executable. This means
that at the moment of creating an executable target the TARGET_POLICY
genex will also be NEW, so we do not take into the account the user
defined CMP0099.
If the CMP0099 policy is not available for a certain CMake version
we skip the TARGET_POLICY check and simply disable propagation of
the object libraries using target_link_options for both user and Qt
libraries. This is applicable for the CMake versions 3.16 and less.
Linking approaches have the following priorities(from higher to lower)
after this change:
- target_link_libraries - works if link order matters not or CMake
version greater equal 3.21.
- target_link_options - works if CMP0099 is set to NEW by user or
if the CMake version is greater than or equal to 3.17 and an
executable is created using Qt functions.
- object library finalizer - works if CMake version is greater equal
3.19 or qt6_finalize_target is called explicitly.
- target_sources - is used when all the other approaches could not
be used.

The tests/auto/cmake project can be configured separately as a
standalone project with qt-cmake, or as part of the overall qtbase
standalone tests.
To do that a bunch of things were done
- Ported all Qt5 strings to Qt6
- Replaced in all projects the use of add_definitions and
include_directories with a target based approach, except for 2 tests
where we check that the old-style approach works, otherwise the
tests would file
- Removed some (possibly unneeded) EGL / OpenGL tests
- Fixed some C++ code
- Added setup code to tests/auto/cmake/CMakeLists.txt to figure out
which modules are available and should be tested
- Fixed Qt6CTestMacros.cmake to be loaded by Qt6Core
- Removed the CMake tests to not be run in qmake builds of Qt because
they would fail anyway
- Enabled the CMake tests to be part of standalone tests
- Disabled auto-passing of the C and CXX compiler cache vars when
cross-compiling so that the tests can somewhat pass on boot2qt.
This is the issue we encountered in
e2b2cd9397
- Ultimately disabled tests for boot2qt, because the -rpath-link
flag is not generated by CMake for some reason.
- Added code to setup the environment when running an executable that
was built as part of the test, so that the proper Qt libraries are
found. This handles both the standalone tests case and separate
project case.
The remaining unported tests are test_import_plugins which requires
quite a bit of work to get some modules and plugins built that were
done as part of the qmake .pro files, test_plugins that checks
some Network plugins which I'm not sure about, and
test_add_big_resource which doesn't work with namespaced builds
and there's no good way of detecting those at the moment either.
