file_fdw: Add on_error and log_verbosity options to file_fdw.

In v17, the on_error and log_verbosity options were introduced for
the COPY command. This commit extends support for these options
to file_fdw.

Setting on_error = 'ignore' for a file_fdw foreign table allows users
to query it without errors, even when the input file contains
malformed rows, by skipping the problematic rows.

Both on_error and log_verbosity options apply to SELECT and ANALYZE
operations on file_fdw foreign tables.
