Previously at least i915 failed to provide an implementation, but
exposed ARB_internalformat_query anyway, leading to crashes when
QueryInternalformativ was called.
Default implementation just returns 1 for everything, so is suitable for
any driver which does not support multisampling.
V2: - Move from intel to core mesa.

Now that we support ARB_texture_multisample, there are multiple targets
accepted for this query, and they may have target-dependent limits, so
pass the target to the driverfunc.
For example, the sampling hardware may not be able to do general
texelFetch() for some format/sample count combination, but the driver
may still be able to implement a reasonable resolve operation, so it can
be supported for renderbuffers.
V2: - Don't break Gallium compile.

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.

This is for the GL_ARB_internalformat_query extension and GLES 3.0.
v2: Generate GL_INVALID_OPERATION if the extension is not supported.
