drm/i915/gt: Relocate compression repacking WA for JSL/EHL
commit 8236820fd767f400d1baefb71bc7e36e37730a1e upstream.
CACHE_MODE_0 registers should be saved and restored as part of
the context, not during engine reset. Move the related workaround
(Disable Repacking for Compression) from rcs_engine_wa_init()
to icl_ctx_workarounds_init() for Jasper Lake and Elkhart
Lake platforms. This ensures the WA is applied during context
initialisation.
