transform: Add NumWorkgroupsFromUniform transform

This transform scans entry points for struct parameters that contain
the num_workgroups builtin, and replace accesses to these members with
a value loaded from a uniform buffer.

This will be used by the HLSL backend to implement the num_workgroups
builtin.
