Bug 1900677 - Recycle DataSourceSurface allocated in CanvasTranslator::LookupSourceSurfaceFromSurfaceDescriptor() if possible r=gfx-reviewers,lsalzman

Add a capability to reuse used DataSourceSurface that was previously used for storing converted video data. The format of converted video's DataSourceSurface is always SurfaceFormat::B8G8R8X8 in this case. Therefore, there is no need to care about transparency during recycling.

When recycled, one last reference is owned by mUsedDataSurfaceForSurfaceDescriptor.

Add argument gfx::DataSourceSurface* aSurface to TextureHost::GetAsSurface(). aSurface may be used as returned DataSourceSurfacefi the TextureHost supports it.

ImageDataSerializer::DataSourceSurfaceFromYCbCrDescriptor() already supports to provide a pre-allocated DataSourceSurface as an argument. CreateSourceSurfaceFromMacIOSurface() is extended to support a pre-allocated DataSourceSurface as an argument.
