Fix validation of COPY FORCE_NOT_NULL/FORCE_NULL for the all-column cases
This commit adds missing checks for COPY FORCE_NOT_NULL and FORCE_NULL
when applied to all columns via "*". These options now correctly
require CSV mode and are disallowed in COPY TO, making their behavior
consistent with FORCE_QUOTE.
Some regression tests are added to verify the correct behavior for the
all-columns case, including FORCE_QUOTE, which was not tested.
Backpatch down to 17, where support for the all-column grammar with
FORCE_NOT_NULL and FORCE_NULL has been added.
