Call ID3D12SharingContract::Present on WebGPU swap buffer destroy

In PIX's D3D12-only mode, there is no way to determine frame boundaries
for WebGPU since Dawn does not manage DXGI swap chains. Without
assistance, PIX will wait forever for a present that never happens.

If we know we're dealing with a swapbuffer texture, inform PIX we've
"presented" the texture so it can determine frame boundaries and use the
texture's contents for the UI.
