Jeff Epler 7f744a2369 Supervisor: move most of systick to the supervisor
This code is shared by most parts, except where not all the #ifdefs
inside the tick function were present in all ports.  This mostly would
have broken gamepad tick support on non-samd ports.

The "ms32" and "ms64" variants of the tick functions are introduced
because there is no 64-bit atomic read.  Disabling interrupts avoids
a low probability bug where milliseconds could be off by ~49.5 days
once every ~49.5 days (2^32 ms).

Avoiding disabling interrupts when only the low 32 bits are needed is a minor
optimization.

Testing performed: on metro m4 express, USB still works and
time.monotonic_ns() still counts up

Jeff Epler be5205d020 usb_hid: Allow USB work to progress while waiting for tud_hid_ready
Otherwise, examples like the one attached to the related issue fail
because tud_hid_ready never returns true.

Testing performed: Adapted the example to nrf particle xenon (it was
handy), removed dependency on IR, verified that the problem occurred
before this change, and that it was fixed after this change.

Closes: #2048

Fix HID buffer lookup
The previous code assumed HID report ids were consecutive. This is
not true in the CircuitPython descriptor where report ids are fixed
for each report type.

Fixes #1617

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.
