Skip ImplWitnessTable::elements_id when generating fingerprints (#7629)

Browse Source 
Implementing interface modifiers causes an infinite loop when generating
fingerprints because the witness value generates a fingerprint that's
dependent on something dependent on the witness value. We've debugged
this to the witness table's `elements_id` field.

This hack is a workaround for creating a new block type whose value is
not codependent with its identity.
