Simplify commit 2c7acd34e2 (cmComputeLinkInformation: add `OBJECT`
libraries as link items, 2023-07-24, v3.28.0-rc1~279^2) using the
existing local variables.
Since commit b6a5382217 (Ninja: depend on language module information
files directly, 2023-02-10, v3.27.0-rc1~502^2), the return value of
`cmCommonTargetGenerator::GetLinkedTargetDirectories` must account for
linked object libraries because they may provide modules (#25112).
These were added by commit b665966933 (cmComputeLinkInformation: track
OBJECT library dependencies, 2023-07-22, v3.27.1~5^2). However, targets
named by `$<TARGET_OBJECTS:...>` sources are also needed (#25365).
The latter were added by commit 22da18b995 (Fortran: Restore support for
TARGET_OBJECTS providing modules, 2023-10-27, v3.28.0-rc4~9^2) and
commit 035302b7e3 (cmComputeLinkDepends: also copy the target from
object link items, 2023-10-27, v3.28.0-rc4~9^2~2). However, their
approach added link entries not actually specified by projects. It also
incorrectly re-used `cmComputeLinkDepends::AddLinkObject` for object
library targets when it is meant for their individual object files.
These problems caused additional regressions (#25417). Revert the
implementation parts of those commits and leave behind an assertion and
comment to help avoid the mistake in the future. Instead, track targets
named by `$<TARGET_OBJECTS:...>` sources with a dedicated member.

This allows for a more graceful transition for projects using C++20
without scanner support (e.g., Clang 15 or GCC 13). While newer
compilers will (needlessly) scan, it allows C++20-using projects to use
older compilers without having to set `CMAKE_CXX_SCAN_FOR_MODULES` to
support newer CMake minimum versions.

Windows 10 supports ANSI colors since v1511. For earlier versions of Windows
installing ANSICON will enable ANSI colors in cmd.exe.
For those setups where the environment is set up with CLICOLOR_FORCE set
to 1 ctest should honor the setting and emit colored ANSI output.

Continue b665966933 (cmComputeLinkInformation: track OBJECT library
dependencies, 2023-07-22) which added explicitly listed `OBJECT`
libraries to the list of targets which the collator needs to consider.
Now also consider targets which provide objects directly to the target
via a `$<TARGET_OBJECT>` source lists.
Also add tests which use target objects directly and through an
`INTERFACE` library with target objects in its own sources.

In some cases `GetShortPathNameW` may not remove all spaces. If that
happens with the path to `rc.exe`, cmcldeps needs to explicitly quote
the path in the command it runs.
This was exposed by commit 50a6e78a82 (cmSystemTools::RunSingleCommand():
Replace cmsysProcess with cmUVProcessChain, 2023-07-25, v3.28.0-rc1~138^2~4)
because the underlying process execution library no longer reconstructs the
command line without quotes around commands without spaces.

Since commit d85238a2f2 (source_group: Fix TREE without FILES,
2023-06-29, v3.28.0-rc1~399^2~1) we incorrectly treat a FILES
argument with no values as if it were not given at all.
Fixes: #25353
C++ module sources should not be included by any other TUs, so their
presence cannot matter for order-only dependencies of the entire target.
Exclude them.
Update CMP0154 to take this into consideration and add tests to the
`CXXModules` suite (which already deals with module support detection).
Prior to 5420639a, execute_process() would open INPUT_FILE, OUTPUT_FILE,
and ERROR_FILE relative to the WORKING_DIRECTORY argument if it was
provided. Restore this behavior for backwards compatibility.

Changing the `timestamp` file to `timestamp_$<CONFIG>` causes some user
projects to break when using Qt versions older than 6.6.
Revert commit fddd0f0443 (Autogen: AUTO*_EXECUTABLE: add support for
per-config values, 2023-06-14, v3.28.0-rc1~96^2~1) pending further
investigation.
Issue: #20074
Under CMP0155's NEW behavior, projects that explicitly enable C++20
support with `set(CMAKE_CXX_STANDARD 20)` may also explicitly
disable scanning with `set(CMAKE_CXX_SCAN_FOR_MODULES OFF)`.
We already propagate `CMAKE_CXX_STANDARD` into `try_compile` test
projects, so propagate `CMAKE_CXX_SCAN_FOR_MODULES` too.
Fixes: #25313
