feat(eink): landscape and portrait builds, 8x13 font in landscape

Browse Source 
The L1 e-ink solo build splits in two, one per screen shape, so each
screen can be laid out for a single shape. Settings > Rotation now only
turns the screen upside down, and the joystick turns with it.

Landscape writes in misc-fixed 8x13 at the panel's own resolution
(EINK_LARGE_FONT); portrait keeps the 6x9. All drawing moves into
EinkGfxDisplay, which the panel driver and the simulator share; the
FreeSans fonts and the CRC32 library go.
