pg_dump: Fix incorrect parsing of object types in pg_dump --filter.

Previously, pg_dump --filter could misinterpret invalid object types
in the filter file as valid ones. For example, the invalid object type
"table-data" (likely a typo for the valid "table_data") could be
mistakenly recognized as "table", causing pg_dump to succeed
when it should have failed.

This happened because pg_dump identified keywords as sequences of
ASCII alphabetic characters, treating non-alphabetic characters
(like hyphens) as keyword boundaries. As a result, "table-data" was
parsed as "table".

To fix this, pg_dump --filter now treats keywords as strings of
non-whitespace characters, ensuring invalid types like "table-data"
are correctly rejected.

Back-patch to v17, where the --filter option was introduced.
