Add D3D12 Backend for MultiDrawIndirect Feature

This CL adds support for the D3D12 backend, which requires emulation of
base vertex and base instance parameters in the indirect arguments.
The indirect draw validation compute pass duplicates the parameters if it is used in the shaders.
MultiDraw capability is supported on all devices with D3D12.
New tests added for MultiDrawIndexedIndirect to test baseVertex and firstInstance.
