f97f8537f3 VS: Model a default target framework
Add fields to the VS generator to select a target framework.
Migrate the existing default for VS 12 .NET CF for Windows CE.

Report the values in `CMAKE_VS_*` variables and use them for
the CSharp compiler id project too.

e9976c8827 Help: Better explain CMAKE_<LANG>_EXTENSIONS_DEFAULT
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.

4a0485be7f cmStandardLevelResolver: Avoid unnecessary flags, fix unset level logic
The changes are part of CMP0128.

When the standard level is unset:
* Flags are added if extension mode doesn't match the compiler's default.
  Previously logic only worked if LANG_EXTENSIONS was ON. Fixes #22224.
* The full flag is used. Previously CMAKE_LANG_EXTENSION_COMPILE_OPTION was
  used. This was only supported for IAR.

Otherwise:
* Avoid adding flags if not necessary per the detected compiler defaults.
* Fixed check for when the requested standard is older. It now matches the
  nearby comments.

I reworded the fallback comment as its logic was a bit difficult to wrap my
head around.

a71f0fc9c7 HIP: Remove ROMClang compiler id and use Clang directly
Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang
compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6) and commit ff0d2858e1
(HIP: Extract clang compiler details from hipcc, 2020-10-21,
v3.21.0-rc1~66^2~5), the separate `ROCMClang` compiler id for `hipcc`
has caused a few problems:

* The compiler id changed from behavior of CMake 3.20 and below,
  breaking projects that already built with `hipcc` treated as `Clang`.

* The implementation of `target_compile_features` was incomplete for
  the `ROCMClang` identity.

* Only `hipcc` was identified as `ROCMClang`, so after it is unwrapped
  to the underlying `clang++`, future runs of new CMake versions on
  an existing build tree would not repeat this.

* Clang should be usable as a HIP compiler without the `hipcc` wrapper.

Remove the `ROMClang` compiler identity, and revise HIP language support
to work directly with a Clang compiler.

Reject direct `hipcc` usage as a HIP compiler.  For now it cannot be
supported because it interferes with flags CMake needs to pass to Clang.

a2e9fe38e4 find_package: Add variable to make package REQUIRED
Add a `CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>` variable is complement
to `CMAKE_DISABLE_FIND_PACKAGE_<PackageName>` with just the opposite
behaviour: it turns non-required find_package call into the required one.

While optional package dependencies usually result in simple and clean
build logic, sometimes people want to be sure those optional
dependencies will be found and used. Examples are reproducible builds
and build instructions for 3rd parties. People choose to make
find_package calls REQUIRED and put them behind an option(). Such
workarounds blend build logic with build environment management and do
not look elegant.
