Seungha Yang 81dde0f5b8 d3d11: Aggregate d3d11 memory usage query for dynamic-usage type decision
Even if one of downstream d3d11 elements can support dynamic-usage memory,
another one might not support it. Also, to support dynamic-usage,
both upstream and downstream d3d11device must be the same object.
