drm/xe: Add support for OOB workarounds
There are WAs that, due to their nature, cannot be applied from a
central place like xe_wa.c. Those are peppered around the rest of the
code, as needed. Now they have a new name: "out-of-band workarounds".
These workarounds have their names and rules still grouped in xe_wa.c,
inside the xe_wa_oob array, which is generated at compile time by
xe_wa_oob.rules and the hostprog xe_gen_wa_oob. The code generation
guarantees that the header xe_wa_oob.h contains the IDs for the
workarounds that match the index in the table. This way the runtime
checks that are spread throughout the code are simple tests against the
bitmap saved during initialization.
v2: Fix prev_name tracking not working when it's empty, i.e. when there
is more than 1 continuation rule.
