drm/xe/guc: refactor ads to use guc_class

Currently in the lrc init flow on the ads side, we loop through each
generic engine class and convert that to the respective guc engine
class. However, with some upcoming changes, it will be better to go the
opposite way and loop through every guc engine class, and convert that
to the generic engine class.

This will be needed in an upcoming patch where we have a new guc engine
class that just matches up to the existing blitter/copy class, but needs
to be treated as a separate entity from the normal copy lrc, when
setting up the ADS.

This also reworks engine_enable_mask to operate on the guc_class, that
way we can easily filter out the PAGING vs normal BSC, when applicable.

As a bonus, this also gets rid of two xe_engine_class_to_guc_class()
users which will be helpful for the next patch.

No functional changes.

v2 (Daniele):
 - Simplify fill_engine_enable_masks() to just loop over all guc
   classes.
