drm/xe/irq: Rename bits used with all engines

drm/xe/irq: Rename bits used with all engines

Two bit fields have similar functionality across the interrupt vectors
but are named "RENDER". Rename them to follow the bspec more closely and
clear any confusion when using them for other engines.

Bspec: 62353, 62354, 62355, 62346, 62345, 63341
