drm/xe/uapi: Fix various struct padding for 64b alignment
Let's respect Documentation/process/botching-up-ioctls.rst
and add the proper padding for a 64b alignment with all as
well as all the required checks and settings for the pads
and the reserved entries.
v2: Fix remaining holes and double check with pahole (Jose)
Ensure with pahole that both 32b and 64b have exact same
layout (Thomas)
Do not set query's pad and reserved bits to zero since it
is redundant and already done by kzalloc (Matt)
v3: Fix alignment after rebase (José Roberto de Souza)
v4: Fix pad check (Francois Dugast)
