For MTL, update the GSC-HECI packet size and the max firmware
response timeout to match internal fw specs. Enforce setting
run-alone bit in LRC for protected contexts.

Changes from prio revs:
   v4: - PAGE_ALIGN the max heci packet size (Alan).
   v3: - Patch #1. Only start counting the request completion
         timeout from after the request has started (Daniele).
   v2: - Patch #3: fix sparse warning reported by kernel test robot.
   v1: - N/A (Re-test)
