drm/xe/xelp: Implement Wa_16010904313

Add XeLP workaround 16010904313.

The description calls for it to be emitted as the indirect context buffer
workaround for render and compute, and from the workaround batch buffer
for the other engines. Therefore we plug into the previously added
respective top level emission functions.

The actual command streamer programming sequence differs from what is
described in the PRM, in that it assumes the listed LRCA offset was
supposed to actually refer to the location of the CTX_TIMESTAMP register
instead of LRCA + 0x180c (which is in GPR space). Latter appears to make
more sense under the assumption that multiple writes are helping with
restoring the CTX_TIMESTAMP register content from the saved context state.
