mesa: Move DepthMode to texture object
GL_DEPTH_TEXTURE_MODE isn't meant to be part of sampler state based on
compatibility profile specifications.
OpenGL specification 4.1 compatibility 20100725 3.9.2:
"... The values accepted in the pname parameter
are TEXTURE_WRAP_S, TEXTURE_WRAP_T, TEXTURE_WRAP_R, TEXTURE_MIN_-
FILTER, TEXTURE_MAG_FILTER, TEXTURE_BORDER_COLOR, TEXTURE_MIN_-
LOD, TEXTURE_MAX_LOD, TEXTURE_LOD_BIAS, TEXTURE_COMPARE_MODE, and
TEXTURE_COMPARE_FUNC. Texture state listed in table 6.25 but not listed here and
in the sampler state in table 6.26 is not part of the sampler state, and remains in the
texture object."
The list of states is in Table 6.24 "Textures (state per texture
object)" instead of 6.25 mentioned in the specification text.
Same can be found from 3.3 compatibility specification.
