mesa/formatquery: Added queries related to texture sampling in shaders

Browse source 
From the ARB_internalformat_query2 specification:

   "- VERTEX_TEXTURE: The support for using the resource as a source for
      texture sampling in a vertex shader is written to <params>.

    - TESS_CONTROL_TEXTURE: The support for using the resource as a source for
      texture sampling in a tessellation control shader is written to <params>.

    - TESS_EVALUATION_TEXTURE: The support for using the resource as a source
      for texture sampling in a tessellation evaluation shader is written to
      <params>.

    - GEOMETRY_TEXTURE: The support for using the resource as a source for
      texture sampling in a geometry shader is written to <params>.

    - FRAGMENT_TEXTURE: The support for using the resource as a source for
      texture sampling in a fragment shader is written to <params>.

    - COMPUTE_TEXTURE: The support for using the resource as a source for
      texture sampling in a compute shader is written to <params>."

For all of them,

   "Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
    If the resource or operation is not supported, NONE is returned."
