libpayload: cbgfx: Allow rotation of the display
Sometimes the display native orientation does not match the device
default orientation, so allow rotation of the framebuffer before
it is displayed on screen.
set_pixel now take coordinates in the rotated coordinate system,
and converts the coordinates before writing to the framebuffer.
Also, screen.size now matches the rotated system (_not_ the
framebuffer size).
BUG=b:132049716
TEST=Boot krane, see that FW screen is orientation properly.
