Framebuffer: Support variable number of framebuffers in the UI
This change defines a macro NUM_FRAME_BUFFERS to set
the desired number of framebuffers to be used by the UI,
instead of hard-coding 2 framebuffers.
Aditional logic has been added to handle the initialization
and destruction of NUM_FRAME_BUFFERS buffers.
