Rollup merge of #106931 - Ezrashaw:docs-e0208, r=compiler-errors 
document + UI test `E0208` and make its output more user-friendly

Cleans up `E0208`'s output a lot. It could actually be useful for someone learning about variance now. I also added a UI test for it in `tests/ui/error-codes/` and wrote some docs for it.

r? `@GuillaumeGomez` another error code, can't be bothered to find the issue :P. Obviously there's some compiler stuff, so you'll have to hand it off.

Part of https://github.com/rust-lang/rust/issues/61137.

925dc37313 Stop using BREAK & CONTINUE in compiler 
Switching them to `Break(())` and `Continue(())` instead.

libs-api would like to remove these constants, so stop using them in compiler to make the removal PR later smaller.

Rollup merge of #106970 - kylematsuda:earlybinder-item-bounds, r=lcnr 
Switch to `EarlyBinder` for `item_bounds` query

Part of the work to finish #105779 (also see https://github.com/rust-lang/types-team/issues/78).

Several queries `X` have a `bound_X` variant that wraps the output in `EarlyBinder`. This adds `EarlyBinder` to the return type of the `item_bounds` query and removes `bound_item_bounds`.

Rollup merge of #104505 - WaffleLapkin:no-double-spaces-in-comments, r=jackh726 
Remove double spaces after dots in comments

Most of the comments do not have double spaces, so I assume these are typos.

Rollup merge of #106829 - compiler-errors:more-alias-combine, r=spastorino 
Unify `Opaque`/`Projection` handling in region outlives code

They share basically identical paths in most places which are even easier to unify now that they're both `ty::Alias`

Rollup merge of #106739 - WaffleLapkin:astconv, r=estebank 
Remove `<dyn AstConv<'tcx>>::fun(c, ...)` calls in favour of `c.astconv().fun(...)`

This removes the need for <>><><><<>> dances and makes the code a bit nicer.

Not sure if `astconv` is the best name though, maybe someone has a better idea?

Rollup merge of #106164 - compiler-errors:check-region-tweak, r=oli-obk 
Move `check_region_obligations_and_report_errors` to `TypeErrCtxt`

Makes sense for this function to live with its sibling `resolve_regions_and_report_errors`, around which it's basically just a wrapper.
