Always use draws instead of clears for ANGLE D3D11
At least for my repro case on a Z620 with an nVidia Quadro K620 and recent drivers, this eliminates the noise artifacts.
It appears that full target clears are broken in ANGLE D3D11.
Note I was never able to repro the bug in the D3D9 or openGL configs.
The bug reproed for both the ES2 and ES3 ANGLE D3D11 configs though.
Bug: 768134
