[IR] enable attaching metadata on ifuncs (#158732)
Teach the IR parser and writer to support metadata on ifuncs, and update
documentation.
In PR #153049, we have a use case of attaching the `!associated`
metadata to an ifunc.
Since an ifunc is similar to a function declaration, it seems natural to
allow metadata on ifuncs.
Currently, the metadata API allows adding Metadata to
llvm::GlobalObject, so the in-memory IR allows for metadata on ifuncs,
but the IR reader/writer is not aware of that.
