Recent SharedImage changes always assumed the presence of a D3D11
device. When graphite runs with D3D12, no D3D11 device was provided
to the D3DImageBackingFactory constructor, causing it to crash
At the same time, since InitializeDirectComposition is always called
with ANGLE's D3D11 device, it incorrectly, returned true for
IsD3DSharedImageSupported and crashed when the renderer process sent
it scanout images.
The CL rearranges GPU initialization such that DirectComposition is
initialized after the Dawn context provider, thus providing it the
correct D3D11 device, or no D3D11 device if there is none.
IsD3DSharedImageSupport is provided with the SharedContextState so it
can learn the truth about there being no D3D11 device.
With these changes, D3DSharedImageFactory is never created and no
scanout images are requested from the renderer process. Graphite on
D3D12 boots and is able to draw basic web pages.
Future CLs will slowly bring back SharedImage capability when Graphite
runs on D3D12.
