[TypeID] Update private typeid definition in DeferredLocInfo (#128968)

The parser's `DeferredLocInfo` uses an uncommon TypeID setup, where it
defines a private TypeID for pointers to the struct.

When using the fallback TypeID mechanism introduced in
#126999, the fallback TypeID
mechanism doesn't support anonymous namespaces, and the
`INTERNAL_INLINE` mechanism doesn't support pointer types.

Explicitly use `SELF_OWNING_TYPE_ID` for this case. This should always
be safe for anonymous namespaces.
