Harden the pre-tyctxt query system against accidental recomputation

While the current compiler has no issues where we `take` and then compute the query again, in rust-lang/rust#105462 I accidentally introduced such a case.

I also took the opportunity to remove `peek_mut`, which is only ever used for `global_tcx` to then invoke `enter`. I added an `enter` method directly on the query.
