Rollup merge of #137604 - davidtwco:host-effect-resolve-vars, r=compiler-errors
trait_sel: resolve vars in host effects In the standard library, the `Extend` impl for `Iterator` (specialised with `TrustedLen`) has a parameter which is constrained by a projection predicate. This projection predicate provides a value for an inference variable but - if the default bound is `const Sized` instead of `Sized` - host effect evaluation wasn't resolving variables first. Added a test that doesn't depend on a rust-lang/rfcs#3729 implementation. Adding the extra resolve can the number of errors in some tests when they gain host effect predicates, but this is not unexpected as calls to `resolve_vars_if_possible` can cause more error tainting to happen.
