mesa: don't include compute resources in MAX_COMBINED_* limits
5 is the maximum number of shader stages that can be used by 1 execution
call at the same time (e.g. a draw call). The limit ensures that each
stage can use all of its binding points.
Compute is separate and doesn't need the 5x multiplier.
