[live-preview] Fix GMB issue with Windows

When GpuRasterization is not available or if there is no support for
D3dSharedImage, rendering GMB frames fails.

The video preview is implemented by painting the video frame into a
tile via PaintCanvasVideoRenderer in the browser compositor. When the
incoming video resource is a GpuMemoryBufferHandle it goes to
GpuMemoryBufferHandleHolder which wraps it in a shared image. That
should work fine if the tile is GPU rasterized, since the video frame
texture to tile texture copy happens on the GPU, but it won't work in
case of software raster since rasterization happens in the browser
process and GPU texture data is unavailable. This CL provides a fix
for that by requesting pre-mapped frames and wraps the
SharedMemoryRegion.
