Wyatt Alt a91b29efc1 fix: scope the Function binding guard on schema evolution to the bound columns (#4204)
A table with one registered Function binding refused every add_columns,
alter_columns, drop_columns and field-metadata update, whatever column
they named. The hazard is narrower: a binding stores the exact Arrow
fields of its inputs, outputs and assignment column, so editing one of
those strands it and the table stops accepting rows. Any other column
was never at risk.

The guard now compares the columns a request names, a rename's target
included, against the set every binding depends on, and refuses only on
an intersection. Local and remote tables apply the same rule. The
blanket guard stays on update and merge insert, which cannot say what
they touch.
