    Add tests for low-level PGLZ [de]compression routines
    
    The goal of this module is to provide an entry point for the coverage of
    the low-level compression and decompression PGLZ routines.  The new test
    is moved to a new parallel group, with all the existing
    compression-related tests added to it.
    
    This includes tests for the cases detected by fuzzing that emulate
    corrupted compressed data, as fixed by 2b5ba2a0a141:
    - Set control bit with read of a match tag, where no data follows.
    - Set control bit with read of a match tag, where 1 byte follows.
    - Set control bit with match tag where length nibble is 3 bytes
    (extended case).
    
    While on it, some tests are added for compress/decompress roundtrips,
    and for check_complete=false/true.  Like 2b5ba2a0a141, backpatch to all
    the stable branches.
