Bryan Bernhart 9c3aefa4bd D3D12: Enable external texture reuse ...

This change allows multiple Dawn textures to be created from the same
D3D11 resource. This avoids re-opening the shared handle by caching the
D3D12 resource outside of the Dawn texture.

Re-opening the handle costs 5-10% of CPU cycles per frame, which far
exceeded syncronization costs.

In a future change, WrapSharedHandle will be depreciated.
