Rollup merge of rust-lang#104675 - SarthakSingh31:issue-101666, r=jyn514

Unsupported query error now specifies if its unsupported for local or external crate

Fixes rust-lang#101666.
I had to move `keys.rs` from `rustc_query_impl` to `rustc_middle`. I don't know if that is problematic. I couldn't think of any other way to get the needed information inside `rustc_middle`.
