llvm::Any had and has several bugs, so we eventually want to replace it
with std::any.

Unfortunately, we cannot do that right now because of bugs in the msvc
standard library.
This patch re-implements llvm::Any as a wrapper around std::any.
With non-msvc compilers or when the msvc version is new enough (the
issue was fixed in VS 2022 17.4) we use std::any internally. On other
versions we fall back to our existing implementation of llvm::Any.
