CMake: Add an llvm-mingw clang version check to preserve_all

llvm has supported preserve_all abi on Windows ABI since
https://github.com/llvm/llvm-project/pull/166436.
This has been in a clang release since 22.1. Do a clang version check to
ensure the compiler is >= 22.1 to enabled preserve_all under
wow64/arm64ec.

This will give a performance boost to applications that require x87 full
precision and a couple other minor things.
