mesa: enable GL_TEXTURE_LOD_BIAS set/get
Earlier comments suggest this was removed from GL core spec but it is
still there. Enabling makes 'texture_lod_bias_getter' Khronos
conformance tests pass, also removes some errors from Metro Last Light
game which is using this API.
v2: leave NOTE comment (Ian)
