The pxf_fdw files were removed in Greenplum via this commit[1] in Nov
2022, which indicated that pxf_fdw should be built from the
greenplum-db/pxf (cloudberry-pxf) repo.

AFAIS, we don't encourage the users to configure the build with the
`--enable-pxf` option in the Cloudberry build. The pxf files in
Cloudberry source are deprecated, right? If so, we can remove these
files too.

Please correct me if I'm wrong.
