drm/xe/xe3p_lpg: Update LRC sizes

Like with previous generations, the engine context images for of both
RCS and CCS in Xe3p_LPG contain a common layout at the end for the
context related to the "Compute Pipeline".

The size of the memory area written to such section varies; it depends
on the type of preemption has taken place during the execution and type
of command streamer instruction that was used on the pipeline. For
Xe3p_LPG, the maximum possible size, including NOOPs for cache line
alignment, is 4368 dwords, which would be the case of a mid-thread
preemption during the execution of a COMPUTE_WALKER_2 instruction.

The maximum size has increased in such a way that we need to update
xe_gt_lrc_size() to match the new sizing requirement. When we add that
to the engine-specific parts, we have:

  - RCS context image: 6672 dwords = 26688 bytes -> 7 pages
  - CCS context image: 5024 dwords = 20096 bytes -> 5 pages
