Fixed #36289 -- Fixed bulk_create() crash with nullable geometry fields on PostGIS.

Swapped to an allow list instead of a deny list for field types to
determine if the UNNEST optimization can be enabled to avoid further
surprises with other types that would require further specialization to
adapt.

Regression in a16eedcf9c69d8a11d94cac1811018c5b996d491.

Thanks Joshua Goodwin for the report and Sarah Boyce for the test.
