[PATCH v2] drm/xe/ptl: Apply Wa_14023061436

[Nirmoy Das]

Enable WMTP for the BTD kernel to address Wa14023061436 by setting the
proper TDL Chicken Bit.

v2: Apply it on engine_was[] as this register is not part of LRC(Matt)
    Apply it for first_render_or_compute in case this gets extended to
    compute only platforms(Matt).
