Implement getBindGroupLayout

This patch makes the |layout| member of the Render|ComputePipelineDescriptor
optional. If it is not provided, a default layout is created from the
ShaderModules provided and used to replace the layout in the descriptor.

Then, pipeline.GetBindGroupLayout may be called to get the existing, or
the computed bind group layout. If no bind group layout exists at the
provided index, an empty bind group layout is returned.
