Rollup merge of #131049 - compiler-errors:more-validation, r=spastorino

Validate args are correct for `UnevaluatedConst`, `ExistentialTraitRef`/`ExistentialProjection`

For the `Existential*` ones, we have to do some adjustment to the args list to deal with the missing `Self` type, so we introduce a `debug_assert_existential_args_compatible` function to the interner as well.
