Move `MetadataLoader{,Dyn}` to `rustc_metadata`.

They're not used in `rustc_session`, and `rustc_metadata` is a more
obvious location.

`MetadataLoader` was originally put into `rustc_session` in #41565 to
avoid a dependency on LLVM, but things have changed a lot since then and
that's no longer relevant, e.g. `rustc_codegen_llvm` depends on
`rustc_metadata`.
