drm/i915/dsb: Implement intel_dsb_gosub()
Add support for the new GOSUB DSB instruction (available on ptl+),
which instructs the DSB to jump to a different buffer, execute
the commands there, and then return execution to the next
instruction in the original buffer.
There are a few alignment related workarounds that need to
be dealt with when emitting GOSUB instruction.
v2: Right shift head and tail pointer passed to gosub command (chaitanya)
v3: Add macro for right shifting head/tail pointers (Animesh)
v4: Fix typo in commit message (Uma)
Add comments explaining why right shifting htp is needed (Animesh)
