Turn vtable_allocation() into a query

This PR removes the untracked vtable-const-allocation cache from the `tcx` and turns the `vtable_allocation()` method into a query.

The change is pretty straightforward and should be backportable without too much effort.

Fixes https://github.com/rust-lang/rust/issues/89598.
