gint: switch away from FX9860G/FXCG50 macros
Not changing much for now, just distilling them into hardware/OS/render macros. Later on the rendering stuff will become more dynamic and down the line I want to unify the APIs more.

* Serial communication

* Make fx9860g projects work out of the box on fxcg50

Bits that need to abstract out into APIs:
|

- display: Toggle backlight (or set level)
|

-> Have a backlight property with min/max values

@ getkey

@ justui jscene

- os: OS interface to access OS info, like in fxos
|

@ usb/setup.c set_strings

@ usb/classes/ff-bulk.c identify command
|

- render: current video mode
|
||||
@ usb/classes/ff-bulk.c capture_vram
|

- gray: make gray engine a subset of t6k11 which then supports two modes

- i1msb

- 2i1msb
