Rework framebuffer classes

Drop (I)MappedFramebuffer, as it doesn't really provide any value, and
have most of the methods be present in IFramebuffer with default
exception throwing implementation.

This gives us simpler way to use the framebuffers, as almost always we
can just use a pointer to IFramebuffer.
