Enable debug messages a new `--find-debug` command-line option or via
the `CMAKE_FIND_DEBUG_MODE` variable.
This work was started by Chris Wilson, continued by Ray Donnelly, and
then refactored by Robert Maynard to collect information into a single
message per find query.

Original behaviour would unconditionally enable WinRT for all projects
so source file flag generation code can acknowledge WinRT being present
and disable it for C language source files. An unintentional result of
that approach is that WinRT is enabled for ALL projects, including C++
projects/source files with no way to disable it
Instead use `CMAKE_VS_WINRT_BY_DEFAULT` as a hint that the platform is
WinRT-by-default and set global `CompileAsWinRT` flag to `false` unless
it was explicitly requested by either `WINRT_COMPONENT` option or `/ZW`
compilation option - similar to what Windows Phone/Windows Store
platform logic does
In case WinRT compilation is enabled for a project by either of
aforementioned methods, C language source file override logic will still
kick in and disable CompileAsWinRT for C source files
Fixes: #20063
The CUDA language failed to persist CMAKE_SIZEOF_VOID_P
and CMAKE_INTERNAL_PLATFORM_ABI, causing find_ calls to fail when
the only enabled language was CUDA. This specifically occurred
when having to locate libraries inside `lib64` directories.
In commit fc3b4caa2e (Memory management: cast functions for managed pointers,
2019-11-18) we added a check to `Source/Checks/cm_cxx17_check.cpp` to avoid
using C++17 mode on a compiler that does not support all our C++17 usage.
Add the check to our bootstrap script too.
