Add PacketBuffer and MTU negotiation support.
PacketBuffer facilitates packet oriented BLE protocols such as BLE
MIDI and the Apple Media Service.

This also adds PHY, MTU and connection event extension negotiation
to speed up data transfer when possible.

Check connection validity after service discovery.
Fixes #2347

Add connection interval and debugging
This also sets TinyUSB to master and to not include its submodules.

It also fixes an old displayio example comment and retries gattc
reads.

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.
