With CMP0155 NEW behavior, we scan C++ sources in targets using C++ 20,
i.e., in which the `cxx_std_20` feature is available. However, our
check for C++ feature availability may incorrectly succeed in two cases:
* MSVC versions from VS 2013 do not model C++ standard levels,
so we assume all features are available as a heuristic to let
projects at least try compiling with them.
* During ABI detection the `CMAKE_CXX20_COMPILE_FEATURES` variable is not
populated so we assume all features are available, knowing that our
ABI detection project does not need them.
For purposes of detecting targets using C++ 20, we do not want to assume
`cxx_std_20` is available, so verify that we really know it is.

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.
The compiler does not yet support everything needed to integrate well
with the MSVC ABI, in particular for runtime library selection and debug
format selection. Document them in FIXME comments and leave this
support undocumented by CMake for now.
Fixes: #24840

These are printed by LLVM-based compiler drivers targeting the MSVC ABI.
In our use case for this, `CMAKE_LINKER` may not yet be known, so do
not include it in the test data.

With CMP0155, filesets with only non-compiled sources do not go through
the collation path that detects it. Detect it explicitly like the Visual
Studio generator does.
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.
