Attachment: Bug 1751824 - Build Windows compiler runtimes like for macOS and Android.

It turns out not only can we successfully build the Windows compiler
runtimes separately like on other platforms, but we can also
cross-compile them! Which saves a tremendous amount of time when
rebuilding the toolchains, since we can now produce the clang-win-cross
toolchain much earlier than waiting for a native build of a windows
clang compiler first.

Attachment: Bug 1751824 - Support passing a clang json config to compiler-rt builds.

And use the clang-13 json for all clang-13-based compiler-rt tasks.
This will ensure we apply all the patches that are intended to be
applied (we may want to split out the compiler-rt patches in the future,
though).

Attachment: Bug 1751824 - Fixup for macos compiler-rt build.

Applying all the patches from build-clang enabled the patch for macos
cross compiles that adds a -target argument based on
LLVM_DEFAULT_TARGET_TRIPLE, that we weren't setting.
