Add PicoDVI support
PicoDVI in CP support 640x480 and 800x480 on Feather DVI, Pico and
Pico W. 1 and 2 bit grayscale are full resolution. 8 and 16 bit
color are half resolution.

Memory layout is modified to give the top most 4k of ram to the
second core. Its MPU is used to prevent flash access after startup.

The port saved word is moved to a watchdog scratch register so that
it doesn't get overwritten by other things in RAM.

Right align status bar and scroll area. This normally gives a few
pixels of padding on the left hand side and improves the odds it is
readable in a case. Fixes #7562

Fixes c stack checking. The length was correct but the top was being
set to the current stack pointer instead of the correct top.
Fixes #7643

This makes Bitmap subscr raise IndexError instead of ValueError
when the index arguments are wrong.

Add initial RP2040 support
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
