Add MIDI 2.0 host mode support
Adding MIDI 2.0 host mode support to Android. MIDI 2.0 peripherals
create an alternative setting for Universal Midi Packets (UMP).
UMP packets can be passed directly through as the host has full
control. Instead of going through the ALSA, UMP packets can be
sent directly through a UsbDeviceConnection.
This CL also adds public apis to expose whether the pipe supports
UMP. This for MidiDeviceInfo in Java and AMidi in c++.
Bug: 201003646
Bug: 214447324
Test: Verified that the MIDI 1.0 path still works as before.
Test: Tested that MIDI 2.0 packets are passed through the pipe
with MIDIScope and MIDIKeyboard
Test: atest MidiSoloTest
Test: atest CtsMidiTestCases
Test: NativeMidiEchoTest
