D3D11: Use dirty bits for applyVertexBuffers. If the vertex array has any dirty or dynamic attribs, we must do an update. Similarly, if a prior state change has left the vertex state invalidated, we do an update. For instance, a program change means we need a new input layout. If there was no such invalidation or dirtyness we can skip the call to InputLayoutCache. This improves the performance of the draw call benchmark (with no state changes) by about 50% on the D3D11 null driver. Increases the frames per second count of the aquarium demo with the passthrough command buffer by about 25% on a test machine.
