DIR_METADATA: add the default test plans

We originally used a subtractive rule for hps-firmware-images (meaning,
run only the hps-cq suite and no other tests) so these default test
plans were not originally included in the CTPv2 migration.

In this commit we are changing it to an additive rule:
https://crrev.com/i/5047592
so add the default test plans too.

We are not trying to exempt these files from normal testing. The hps-cq
suite just runs some specialised HPS-specific camerabox tests, we still
want to run HW/VM tests as normal.

BUG=b:250660161
TEST=none
