MDEV-29069 follow-up: improve DEFAULT rules

previously, fields with DEFAULTs were allowed just when expression is
deterministic. In case of online alter, we should recursively check that
underlying fields of expression also either have explicit values, or
have DEFAULT following this validity rule.

MDEV-29069 ER_KEY_NOT_FOUND on online autoinc addition + concurrent DELETE

We can't rely on keys formed with columns that were added during this
ALTER. These columns can be set with non-deterministic values, which can
end up with broken or incorrect search.

The same applies to the keys that contain reliable columns, but also have
bogus ones. Using them can narrow the search, but they're also ignored.

Also, added columns shouldn't be considered during the record match. To
determine them, table->has_value_set bitmap is used.

To fill has_value_set bitmap in the find_key call, extra unpack_row call
has been added.

For replication case, extra replica columns can be considered for this
case. We try to ignore them, too.
