CFI: Support function pointers for trait methods
Adds support for both CFI and KCFI for attaching concrete and abstract types to functions. KCFI does this through generation of `ReifyShim` on any function pointer that could go in a vtable, and checking the `ReifyReason` when emitting the instance. CFI does this by attaching both the concrete and abstract type to every instance. TypeID codegen tests are switched to be anchored on the left rather than the right in order to allow emission of additional type attachments. Fixes #115953
