  [GISel] Remove remainder of the concept of an invalid RegisterBank. (#71118)

RegisterBank no longer has a default constructor so there's no way to
create an invalid register bank.

Remove InvalidID and the isValid method.

Replace the one use of isValid outside of RegBank with a check that the
ID matches so there's still some check of sanity.
