[llvm] Support llvm::Any across shared libraries on windows (#108051)
This is part of the effort to support for enabling plugins on windows by
adding better support for building llvm as a DLL. The export macros used
here were added in #96630

Since shared library symbols aren't deduplicated across multiple
libraries on windows like Linux we have to manually explicitly import
and export `Any::TypeId` template instantiations for the uses of
`llvm::Any` in the LLVM codebase to support LLVM Windows shared library
builds.
This change ensures that external code, including LLVM's own tests, can
use PassManager callbacks when LLVM is built as a DLL.

I also removed the only use of llvm::Any for LoopNest that only existed
in debug code and there also doesn't seem to be any code creating
`Any<LoopNest>`
