mesa: Add driver method to determine the possible sample counts
Use this method in _mesa_GetInternalformativ for both GL_SAMPLES and
GL_NUM_SAMPLE_COUNTS.
v2: internalFormat may not be color renderable by the driver, so zero
can be returned as a sample count. Require that drivers supporting the
extension provide a QuerySamplesForFormat function. The later was
suggested by Eric Anholt.
