Note: I left behind lcd_bitmap in features.txt, because removing it
would require considerable work in the manual and the translations.

HAVE_LCD_BITMAP is now redundant.
lcd_bitmap is always-on in features.txt so manual and lang strings
don't have to change

Requires addition of viewports and alternate framebuffers to greylib
which are essentially similar to the core implementation except that
the framebuffer can be any size and relationship to a viewport. Drawing
is always fully clipped to the intersecting area.
Adapt oscilloscope.c to the API change. FFT will use the new features
(later update).
Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from
plugin API (must be made incompatible now).
