tools/testing/cxl: Enable zero sized decoders under hb0
The kernel now allows committed zero-size HDM decoders so BIOS can lock
empty decoders; cxl_test needs to exercise that path.
Add a mock_zero_size_decoders module parameter (default off). When set,
the special endpoints under host-bridge0 (cxl_mem.0 and cxl_mem.4)
commit decoders 1 and 2 as zero-size + locked above the decoder[0]
auto-region, mirrored on the parent switch and host bridge. The mocks
take a real zero-size DPA reservation, like enumeration of real
hardware, so commit_end lands on a zero-size decoder and the
reservation, poison-by-endpoint, and teardown paths all run.
