Raph Levien 0762cc763c Implement clear_buffers on Metal 
Since clearing functionality is not built-in, use a compute shader.

Simplify tests greatly; they don't need the workaround.

Raph Levien 657f219ce8 Better DX12 descriptor management 
Reduce allocation of descriptor heaps. This change also enables clearing
of buffers, as the handles are needed at command dispatch time.

Also updates the tests to use clear_buffers on DX12. Looking forward to
being able to get rid of the compute shader workaround on Metal.

This is a followup on #125, and progress toward #95
