drm/i915/gen11: enable support for headerless msgs

Setting bit5 (headerless msg for preemptible GPGPU context) of SAMPLER_MODE
register to enable support for the headless msgs on gen11. None of existing
use cases will be affected by this as this change makes both types of
message - headerless and w/ header supported at the same time. It also
complies with the new recommendation for the default bit value for the
next gen.

v2: rewrote commit message to include more information
v3: setting the bit in icl_ctx_workarounds_init()
