    state_tracker: Move the format test out to be an actual unit test.
    We want errors in the table to show up as unit test failures in MRs.
    Also keeps unit test code out of the built drivers.

What linker are you using to always see these undefined references to unused symbols?

This MR should fix it:

I'll make a proper fix replacing `libmesa_util` with `idep_mesautil` which should avoid this ever happening again.
