drm/xe/xe2: Add initial workarounds

Add the initial collection of gt/engine/lrc workarounds.
While at it, add some newlines around the platform/IP comments to make
them consistent across all workarounds.

v2:
  - FF_MODE is an MCR register (Matt Roper)
  - Group 18032247524 with other Xe2 workarounds (Matt Roper)
  - Move WA changing PSS_CHICKEN to lrc_was[] as for Xe2 that register
    is part of the render context image (Matt Roper)
  - Apply WA 16020518922 only on render engine (Matt Roper)
