  [clang] [docs] Clarify the issue with compiler-rt on Windows/MSVC (#106875)

Compiler-rt does support Windows just fine, even if outdated docs pages
didn't list it as one of the supported OSes, this is being rectified in
https://github.com/llvm/llvm-project/pull/106874.

MinGW is another environment configuration on Windows, where compiler-rt
or libgcc is linked in automatically, so there's no issue with having
such builtins functions available.

For MSVC style environments, compiler-rt builtins do work just fine, but
Clang doesn't automatically link them in. See e.g.
https://discourse.llvm.org/t/improve-autolinking-of-compiler-rt-and-libc-on-windows-with-lld-link/71392
for a discussion on how to improve this situation. But none of that
issue is that compiler-rt itself wouldn't support Windows.
