refactor: Remove defunct attributes.h includes

Since the removal of NODISCARD in 81d5af42f4dba5b68a597536cad7f61894dc22a3,
the only attributes def is LIFETIMEBOUND, and it's included in many more
places that it is used.

This removes all includes which do not have an associated use of LIFETIMEBOUND,
and adds it to the following files, due to their use of the same:
* src/validationinterface.h
* src/script/standard.h
