mesa: allow internalformat_query with multisample texture targets

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.
