Use GpuMemoryBuffers for OffscreenCanvas

This CL Makes use of GpuMemoryBuffers in cases where the canvas context
is not accelerated but the compositor is. This includes WebGL
contexts that are rendered using swiftshader.

GpuMemoryBuffers will also be used for GPU-accelerated canvases on
platforms that support gfx::BufferUsage::SCANOUT (i.e. MacOS and
Ozone).
