Split displayio hardware support from core
These are moved:
* Display -> busdisplay.BusDisplay
* FourWire -> fourwire.FourWire
* EPaperDisplay -> epaperdisplay.EPaperDisplay
* I2CDisplay -> i2cdisplaybus.I2CDisplayBus

`paralleldisplay` is now `paralleldisplaybus` (and registered as
`paralleldisplay` too).

Bus related helpers are split out of display_core into bus_core.
It is in still displayio since it is a dependency of both
busdisplay and epaperdisplay.

Fixes #7667

Improve framebufferdisplay.refresh()
Now the defaults make it easy to refresh when you want. It matches
the displayio.Display().refresh() behavior.

FramebufferDisplay: dirty rows are physical
.. so they need a correct row count, which could be the "core.width"
of a 90/180 rotated display.

While I discovered this on the very unusual 320x960 display it could have
affected any framebuffer display that was taller than it was wide,
including sharp memory displays and rgbmatrix displays.

Add address_little_endian for displayio
Add address_little_endian for epaper displays with little endian
(low byte first) addresses.

Also clears allocated display and display bus memory so it has a
known state. The acep member wasn't always set so it varied
accidentally.

Fixes #7560. May fix #7778. Fixes #5119.

Add Bangle.js 2, JDI memory displays and ACeP epd
This 2-in-1 PR started with the goal of support the Bangle.js 2
smartwatch with *no USB*.
* Adds "secure" DFU build support with a committed private key.
* Adds 3-bit color support with one dummy bit for the JDI memory display
* Allows nrf boards to have a board_background_task() run in RUN_BACKGROUND_TASK.
  This is needed because the Bangle.js 2 uses the watchdog to reset.
* Renamed port_background_task() to port_background_tick() to indicate it
  runs on tick, not RUN_BACKGROUND_TASK.
* Marks serial connected when the display terminal is inited. This means
  that safe mode messages show up on the display.

ACep, 7-color epaper displays also pack 3 bits in 4. So, I added that
support as well.
* Adds 3-bit ACeP color support for 7-color e-paper displays. (Not
  watch related but similar due to color depth.)
* Allows a refresh sequence instead of a single int command. The 7" ACeP
  display requires a data byte for refresh.
* Adds optional delay after resetting the display. The ACeP displays
  need this. (Probably to load LUTs from flash.)
* Adds a cleaning phase for ACeP displays before the real refresh.

For both:
* Add dither support to Palette.
* Palette no longer converts colors when set. Instead, it caches
  converted colors at each index.
* ColorConverter now caches the last converted color. It should make
  conversions faster for repeated colors (not dithering.)

Initial broadcom port for Raspberry Pi
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.

There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
  themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
  mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
  and unnecessary for the vast majority of builds.

Fixes #4314

Jeff Epler 88d07ef35b displayio: further ensure just one start_terminal call
@cwalther determined that for boards with 2 displays (monster m4sk),
start_terminal would be called for each one, leaking supervisor heap
entries.

Determine, by comparing addresses, whether the display being acted on
is the first display (number zero) and do (or do not) call start_terminal.

stop_terminal can safely be called multiple times, so there's no need
to guard against calling it more than once.

Slight behavioral change: The terminal size would follow the displays[0]
size, not the displays[1] size

Jeff Epler 774f2e16ba displayio, framebufferio: Remove spurious call to supervisor_start_terminal
A call to supervisor_start_terminal remained in
common_hal_displayio_display_construct and was copied to other display
_construct functions, even though it was also being done in
displayio_display_core_construct when that was factored out.

Originally, this was harmless, except it created an extra allocation.
When investigating #3482, I found that this bug became harmful,
especially for displays that were created in Python code, because it
caused a supervisor allocation to leak.

I believe that it is safe to merge #3482 after this PR is merged.

Jeff Epler 71c63c2812 FramebufferDisplay: Don't set rotation via core_construct
The expectations of displayio.Display and frambufferio.FramebufferDisplay
are different when it comes to rotation.

In displayio.Display, if you call core_construct with a WxH = 64x32
and rotation=90, you get something that is 32 pixels wide and 64 pixels
tall in the LCD's coordinate system.

This is fine, as the existing definitions were written to work like this.
With framebuffer displays, however, the underlying framebuffer (such as
RGBMatrix) says "I am WxH pixels wide in my coordinate system" and the
constructor is given a rotation; when the rotation indicates a transpose
that means "exchange rows and columns, so that to the Groups displayed
on it, there is an effectively HxW pixel region for use".

Happily, we already have a set_rotation method.  Thus (modulo the time
spent debugging things anyway:) the fix is simple: Always request no
rotation from core_construct, then immediately fix up the rotation
to match what was requested.

Testing performed: 32x16 RGBMatrix on Metro M4 Express (but using
the Airlift firmware, as this is the configuration the error was reported
on):
 * initially construct display at 0, 90, 180, 270 degrees
 * later change angle to 0, 90, 180, 270 degrees
 * no garbled display
 * no safe mode crashes

Split pulseio.PWMOut into pwmio
