libcamera: framebuffer: Make FrameBuffer class Extensible

Implement the D-Pointer design pattern in the FrameBuffer class to allow
changing internal data without affecting the public ABI.

Move the request_ field and the setRequest() function to the
FrameBuffer::Private class. This allows hiding the setRequest() function
from the public API, removing one todo item. More fields may be moved
later.
