lima: add lod-bias support

Arno Messiaen requested to merge arnomessiaen/mesa:lima-ppir_lod_bias into master

This MR aims at adding lod-bias support from FS GLSL to lima.

This MR fixes the following piglit tests (when tiling is enabled):

  • glsl-fs-texture2d-bias
  • glsl-fs-texture2dproj-bias
  • glsl-fs-texture2dproj-bias-2
  • glsl-fs-texturecube-2-bias
  • glsl-fs-texturecube-bias
  • glsl-fs-texturelod-01
  • glsl-lod-bias
  • zero-tex-coord bias
  • texture2d-computed-coordinate

TODO:

  • Check if bias parameter coming from uniform / varying work ==> done (both work)
  • Fix pipeline ==> pipeline seems to pass, also with lima jobs enabled
