Replace scrolling with wraparound in graphical debug
...
Inspired by how Haiku does printing for its kernel debugger, this commit
gets rid of the scrolling when the bootlog reaches the end of the screen
and instead wraps around to the start of the screen. Between the last
written line and the first visible written line there is always a blank
line to provide visual separation.
Getting rid of the scrolling significantly simplifies the implementation
of graphical debug and removes the need for double buffering for
performance as we no longer need to read back the framebuffer when
scrolling which is very expensive on write-combining memory like the
framebuffer.
