Auto merge of #125001 - compiler-errors:uplift-trait-predicate, r=lcnr

Uplift various `*Predicate` types into `rustc_type_ir`

Uplifts `ProjectionPredicate`, `ExistentialTraitRef`, `ExistentialProjection`, `TraitPredicate`, `NormalizesTo`, `CoercePredicate`, and `SubtypePredicate`.

Adds `rustc_type_ir_macros`, which semi-duplicates the derive for `TypeVisitable`, `TypeFoldable`, and `Lift`, but in a way that is interner-agnostic.

Moves `rustc_type_ir::trait_ref` to `rustc_type_ir::predicate`. The specific placement of all these structs doesn't matter b/c of glob imports, tho.
