If validity_ptr points to buffer, just pass the buffer

Same here, pass just the buffer and derive ptr from it

Technically this will slice the class to base's validity, but as derived class doesn't have any members, it's fine. Worth adding a comment

I don't think this is right as TemplatedValidityMask(V* ptr, idx_t capacity) constructor sets the pointer but doesn't change validity_data, so these two aren't derived.
