Auto merge of #80090 - jyn514:tcx-in-render, r=GuillaumeGomez 

Pass a `TyCtxt` through to `FormatRender`

This is the next step after https://github.com/rust-lang/rust/pull/79957 for https://github.com/rust-lang/rust/issues/76382. Eventually I plan to use this to remove `stability`, `const_stability`, and `deprecation` from `Item`, but that needs more extensive changes (in particular, https://github.com/rust-lang/rust/pull/75355 or something like it).

This has no actual changes to behavior, it's just moving types around.
