Fixes to pipeline layout compatibility.

For pipeline layout compatibility, consume the Metal resource indexes in this order:
- Consume a fixed number of Metal buffer indexes for Metal argument buffers,
  but only consume them if Metal argument buffers are not being used.
- Consume push constants  Metal buffer index before descriptor set resources,
  but only consume it if the stage uses push constants.
- Consume descriptor set bindings.

In MVKPipelineLayout, separate tracking resource counts from push constants
indexes, and move push constant indexes ahead of descriptor bindings.
In MVKPipeline, track which stages use push constants.
Remove unused and obsolete function declaration in MVKDescriptorSet.h.
