Switch to port_serial_* hooks
This makes it easier to integrate port specific serial alongside
the common approaches.

Start of USB host API
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)

Jeff Epler 694af3dd23 main: redesign boot_out.txt writing
New design:
 * capture output to a vstr
 * compare the complete vstr to boot_out.txt
 * rewrite if not a complete match

This is resilient against future changes to the automatic
text written to boot_out.txt.

This also fixes rewriting boot_out.txt in the case where
boot.py prints something.

Perhaps it also saves a bit of code space. Some tricks:
 * no need to close a file in read mode
 * no need to switch on/off USB write access, going down to the
   oofatfs layer doesn't check it anyway

Jeff Epler dfa7c3d32d codeformat: Fix handling of `**`
After discussing with danh, I noticed that `a/**/b` would not match `a/b`.

After correcting this and re-running "pre-commit run --all", additional
files were reindented, including the codeformat script itself.

Jeff Epler 28043c94b5 supervisor: Improve serial connection detection
These changes remove the caveat from supervisor.runtime.serial_connected.

It appears that _tud_cdc_connected() only tracks explicit changes to the
"DTR" bit, which leads to disconnects not being registered.

Instead:
 * when line state is changed explicitly, track the dtr value in
   _serial_connected
 * when the USB bus is suspended, set _serial_connected to False

Testing performed (using sam e54 xplained):  Run a program to show
the state of `serial_connected` on the LED:
```
import digitalio
import supervisor
import board

led = digitalio.DigitalInOut(board.LED)
while True:
    led.switch_to_output(not supervisor.runtime.serial_connected)
```

Try all the following:
 * open, close serial terminal program
    - LED status tracks whether terminal is open
 * turn on/off data lines using the switchable charge-only cable
    - LED turns off when switch is in "charger" position
    - LED turns back on when switch is in Data position and terminal is
      opened (but doesn't turn back on just because switch position is
      changed)

Move atmel-samd to tinyusb and support nRF flash.
This started while adding USB MIDI support (and descriptor support is
in this change.) When seeing that I'd have to implement the MIDI class
logic twice, once for atmel-samd and once for nrf, I decided to refactor
the USB stack so its shared across ports. This has led to a number of
changes that remove items from the ports folder and move them into
supervisor.

Furthermore, we had external SPI flash support for nrf pending so I
factored out the connection between the usb stack and the flash API as
well. This PR also includes the QSPI support for nRF.

Scott Shawcroft 6839fff313 Move to ASF4 and introduce SAMD51 support. (#258)
* atmel-samd: Remove ASF3. This will break builds.

* atmel-samd: Add ASF4 for the SAMD21 and SAMD51.

* Introduce the supervisor concept to facilitate porting.

The supervisor is the code which runs individual MicroPython VMs. By
splitting it out we make it more consistent and easier to find.

This also adds very basic SAMD21 and SAMD51 support using the
supervisor. Only the REPL currently works.

This begins the work for #178.
