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.

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).
Run the script:
Utilities/Sphinx/update_versions.py --since v3.27.0 --overwrite
Manually remove directives added to new documentation of existing
environment variables.
Fix indentation of the `versionadded` markup added by commit 634079b86d
(cmGeneratorExpressionEvaluator: Short-circuit boolean operators,
2023-09-11) to render the note in the appropriate scope.

Now that scanning support is no longer experimental, the logic for
whether or not to scan C++ 20 sources is now important because all
projects are now exposted to the logic. Make the scanning rules explicit
in the documentation and rework the queries to localize all of the
associated logic.
A policy to handle the ultimate fallback logic will be implemented in a
following commit.
Improve the documentation from commit 46896d98bb (foreach(): loop
variables are only available in the loop scope, 2021-04-25,
v3.21.0-rc1~245^2) to follow policy documentation convention.

Since refactoring in commit 0a5aeaf302 (cmCTestRunTest: Consolidate test
timeout selection logic, 2023-05-04, v3.27.0-rc1~120^2) we accidentally
truncate `--timeout` values to ctest's default `TimeOut`. Fix the
logic to prefer the flag whenever the `TIMEOUT` property is not set.
In combination with the prior refactoring, this also fixes a bug that
caused `--timeout` values of 10000000 seconds or more to be ignored.
