Render: Introduce render_frame_finish RenderEngine callback

Allows to inform the engine that nothing else will be rendered for the
current frame and that the engine can perform post-processing of any
pending result.

For example, this allows the engine to free its memory, read all files
from disk and write them to Blender.

Currently no functional changes, just preparing API for the further
development of Cycles on-disk tile storage.
