Add a TexSubImage benchmark.
Currently we are about 2x as slow on this micro-benchmark in D3D11.
Preliminary testing suggests using CopySubresourceRegion gives
improved performance across the board, but testing could disprove
this hypothesis.
Modified from a sample from bajones.

Only use direct buffers for static data in D3D11.
For highly dynamic data, which gets updated every frame, or almost
every frame, we're better off using our existing dynamic buffer
path. We could further optimize the dynamic buffer path by only
uploading changed data every frame.
