mesa: Do proper format error checks for GenerateMipmap in ES 3.x.
According to the OpenGL ES 3.2 spec's description of GenerateMipmap:
"An INVALID_OPERATION error is generated if the levelbase array was not
specified with an unsized internal format from table 8.3 or a sized
internal format that is both color-renderable and texture-filterable
according to table 8.10."
Similar text exists in the ES 3.0 specification as well.
Our existing rules are pretty close, but miss a few things. The
OpenGL specification actually doesn't have any text about internal
format checking - our existing code comes from a Khronos bug report.
The ES 3.x spec provides a clearer description.
Fixes dEQP-GLES3.functional.negative_api.texture.generatemipmap and
dEQP-GLES2.functional.negative_api.texture.generatemipmap_zero_level
_array_compressed.
