PtpFilter: Introduce Bluetooth Magic Trackpad 2 support (#399)
Introduce Bluetooth support, it works fine now with some minor rough edges in the pairing routine. Pairing might take a disconnect to complete due to the state machine in Windows HID stack (it should succeed on the first try for 99% scenarios though.) Once paired, it works well with on-demand connects and disconnects. Introduce the PTP filter driver, which will be the future home for all current driver implementation. Eventually, all drivers will be merged into the single one and others got removed. The PTP filter driver reuses Windows HID transportation stack to simplify our driver's logic, make transportation more resilient to system failure and reduces power consumption (especially helpful on laptops.) Currently the PTP filter driver supports Magic Trackpad 2 via both USB and Bluetooth mode.
