Rollup merge of #112443 - compiler-errors:next-solver-opportunistically-resolve-regions, r=lcnr 
Opportunistically resolve regions in new solver

Use `opportunistic_resolve_var` during canonicalization to collapse some regions.

We have to start using `CanonicalVarValues::is_identity_modulo_regions`. We also have to modify that function to consider responses like `['static, ^0, '^1, ^2]` to be an "identity" response, since because we opportunistically resolve regions, there's no longer a 1:1 mapping between canonical var values and bound var indices in the response...

There's one nasty side-effect -- one test (`tests/ui/dyn-star/param-env-infer.rs`) starts to ICE because the certainty goes from `Yes` to `Maybe(Overflow)`... Not exactly sure why, though? Putting this up for discussion/investigation.
