40a47d41df samd: background: Allow monitoring time taken in background task 
If you define MONITOR_BACKGROUND_TASK, then a physical output pin
(Metro M4 Express's "SCL" pin by default) will be set HIGH while in
the background task and LOW at other times

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

2bdccf03a7 cpb: define the SPEAKER_ENABLE_PIN 
This allows the board to disable the onboard speaker until explicitly
enabled in user code.

Testing performed on a CPB:
 * Touching the AUDIO pin with a fingertip no longer generates noise/buzz
 * Generating a waveform with `simpleio.tone` produces no sound by default
 * When the board.SPEAKER_ENABLE is configured as a digital output and
   set True, `simpleio.tone` does produce sound

Note that while guides should include information about SPEAKER_ENABLE, it's
possible that some users who omitted it could view this as a breaking change.
They can fix it by simply adding code similar to

    speaker_enable = digitalio.DigitalInOut(board.SPEAKER_ENABLE)
    speaker_enable.direction = digitalio.Direction.OUTPUT
    speaker_enable.value = True

before using the internal speaker.

Closes: #2258

Track unadjusted PWM duty cycle to avoid accumulating conversion errors 
Fixes #2086

When the frequency of a `PWMOut` is change it re-sets the PWM's duty cycle as
well, since the registers have to be re-calculated based on the new frequency.
Unfortunately, `common_hal_pulseio_pwmout_get_duty_cycle`
will return a value very close to, but not exactly, the value passed to `common_hal_pulseio_pwmout_set_duty_cycle`. If the frequency is modified
without the calling code also re-setting the duty cycle then the duty cycle
will decay over time. This fixes that problem by tracking the unadjusted duty
cycle and re-setting the duty cycle to that value when the frequency is changed.

Refine _bleio 
This PR refines the _bleio API. It was originally motivated by
the addition of a new CircuitPython service that enables reading
and modifying files on the device. Moving the BLE lifecycle outside
of the VM motivated a number of changes to remove heap allocations
in some APIs.

It also motivated unifying connection initiation to the Adapter class
rather than the Central and Peripheral classes which have been removed.
Adapter now handles the GAP portion of BLE including advertising, which
has moved but is largely unchanged, and scanning, which has been enhanced
to return an iterator of filtered results.

Once a connection is created (either by us (aka Central) or a remote
device (aka Peripheral)) it is represented by a new Connection class.
This class knows the current connection state and can discover and
instantiate remote Services along with their Characteristics and
Descriptors.
