rhi: d3d: Fix resource binding mismatch with multiple passes
The resetShaderResources() done when starting a render or compute pass
purges all vertex, index, SRV, and UAV bindings. This will be optimized
at a later point, but until then the command buffer's state should be
updated accordingly, otherwise certain use cases end up with incorrect
rendering results due to not binding vertex/index/shader resources
as appropriate.
This fixes the shadowmap example on d3d.
