Cleanup shared memory handling in DesktopCapturer interface.

Previously shared memory buffers for DesktopCapturer were created
using DesktopCapturer::Callback::CreateSharedBuffer(). That made it
difficult to proxy DesktopCapturer interface from one thread to another.
This CL adds SharedBufferFactory interface that's allowed to be called
on a background thread. This also simplifies clients that don't
need to use shared memory, as they no longer need to override
CreateSharedBuffer().
