Extend the logic from commit 08c5b3eff0 (GNUtoMS: Add search path for VS
2019 environment scripts, 2020-01-09, v3.16.3~15^2) to consider VS 2022
paths too.
Fixes: #22847
Explain that this represents the compiler's default and mustn't be modified
by the user. Clarify when it's used as the default.
Additionally:
* Add a reference to it in cmake-compile-features in text explaining the
feature.
* Add explanations for the default initialization by
`CMAKE_<LANG>_EXTENSIONS_DEFAULT` to all `<LANG>_EXTENSIONS` pages and
references to CMP0128.
* Slightly reduce the wordiness of the default initialization explanations by
removing an unnecessary "it is".
Fixes#22828.
The CTestTestCrash tries to force a crash by dereferencing a NULL
pointer. The oneAPI 2021.4 C compiler notices that the pointer and the
value fetched from the pointer are never used and optimizes away the
dereferencing of the NULL pointer, which prevents the crash, causing
the test to fail.
This change adds the `volatile` keyword the pointer to prevent the
compiler optimizing it away. Removing a reference to a `volatile`
variable is illegal because access to a `volatile` variable could have
side effects not observable by the compiler.

Windows provide a "python" executable like this:
%USERPROFILE%\AppData\Local\Microsoft\WindowsApps\python.exe
It is actually a Windows app exec link. If it points to an app
installer, avoid mistaking it for a working Python.

In commit 0723b2c935 (MPI: Add fallback detection code for MPI when cross
compiling, 2021-09-17, v3.22.0-rc1~89^2) the FindPkgConfig module was
included directly. This produces warnings like:
The package name passed to `find_package_handle_standard_args` (PkgConfig)
does not match the name of the calling package (MPI).
Use `find_package(PkgConfig)` instead, as other find modules do.
Fixes: #22823
Previously the `CMAKE_GENERATOR_INSTANCE` value was used only to filter
the instances reported by the Visual Studio Installer tool. If the
specified install location is not known to the VS Installer, but the
user provided a `version=` field, check for the installation directly
on disk.
Fixes: #21639, #22197
