Web MIDI: remove unused USB API based Android backend
As now all chromium supporting Android versions has the native MIDI API
that was introduced at Android M, we don't need the USB based backend
any more. As some devices don't support it by device vendor's decision,
and still we have such a bot for Android Auto, this CL added checks to
skip relevant tests on such a bot.
Ensured as the real-world use was already 0.
