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.

Jeff Epler fae6e29546 nrf: PWMAudioOut: deactivate PWM when deinitting self
.. otherwise, when an AudioPWMOut object was deinitted without being
explicitly stop()ped, it would use up a slot in active_audio[]; the
5th iteration would create a non-working audio object which would just
buzz instead of playing the right thing.

jepler d39c85e3f5 nRF: Change analog reference to VCC(/4)
@ladyada says:
"having this be adjustable (reference) would be ideal cause you can get
absolute voltages but for now, VCC/4 + 4x matches every other chip :)"

... and indeed doing it this way happens to give a much more steady
reading when using a VCC-referenced resistance, and so many of the simple
things you'd wire up are actually VCC-referenced anyway.

jepler f38ee42874 nrf: Add i2s audio output
Testing performed: I used a Particle Xenon with a HDA1334 I2S DAC.
I played a variety of mono 16-bit samples at 11025 and 22050Hz nominal
bit rates.  With this setup, all the 11025Hz samples sound good.
I tested play, pause,  and loop functionality.

During some runs with 22050Hz samples, there were glitches.  However,
these may have only occurred during runs where I had set breakpoints
and watchpoints in gdb.

I also tested with a MAX98357A I2S amplifier.  On this device, everything
sounded "scratchy".  I was powering it from 5V and the 5V rail seemed
steady, so I don't have an explanation for this.  However, I haven't
tried it with a SAMD board.

Jeff Epler 77bc1ba03e nrf: PWMAudioOut: Remove the need to wait in "pause"
The original formulation was because I saw the need to avoid a transition
from playing to stopped exactly when a resume was taking place.  However,
@tannewt was concerned about this pause causing trouble, because it could
be relatively lengthy (several ms even in a typical case).

After reflection, I've convinced myself that updating the registers
in this order in resume avoids a window where a "stopped" event can
be missed as long as the shortcut is updated first.

Testing re-performed: pause/resume testing of looped RawSample and
WaveFile audio sources.

Jeff Epler 4bae29b925 nrf: enable link-time optimization
Testing performed: installed freshly built .uf2 on a Particle Xenon.
Checked that circuitpython still starts.
Checked that the size of all .uf2 files for nrf builds are plausible.

Aside from memory savings, the performance of Python code (pystone)
increased by about +14%.

However, this adds about 12-16 seconds to each nrf build.

Jeff Epler a183425e00 ports/nrf: Implement audioio.AudioOut using PWM
This implements AudioOut, with known caveats:
 * pause/resume are not yet implemented (this is just a bug)
 * at best, the sample fidelity is 8 bits (this is a hardware limitation)

Testing performed:

My test system is a Particle Xenon with a PAM8302 op-amp
https://www.adafruit.com/product/2130 and 8-ohm speaker.  There's no
analog filtering between the Xenon's PWM pin and the "A+" input of
the amplifier; the "A-" pin is disconnected.  It is powered from
VUSB.

I used pin D4, which is *NOT* listed as a low-speed-only pin, but
the code does NOT switch the pin to high drive.  This is related to
an open issue for general inability to set drive level for pins
being used by a "special function" on nrf:
https://github.com/adafruit/circuitpython/issues/1270

Nothing about the code I've written should limit the usable pins.

All samples I played were 16-bit, generally monophonic at 11025Hz
and 22050Hz from the Debian LibreOffice package.
