MIDI: Add test for MidiEventMultiScheduler
This CL adds a new folder in frameworks/base for MIDI tests. This folder can act as a folder for unit tests. A new test is added for MidiEventMultiScheduler. com.android.internal.midi is used so this test has to be here. Bug: 266473128 Test: atest MidiTests --rebuild-module-info Change-Id: If0d33bd46f8c8adf3a3425888f469f942594aca9
