Mixer: selectively remove PlayHandles in removePlayHandles()

Browse Source 
This commit allows finer control of which kind of PlayHandles get
removed in Mixer::removePlayHandles().

This is now used by InstrumentTrack which only removes NotePlayHandles
in InstrumentTrack::silenceAllNotes(). Fixes broken preview of resources
loaded by IPH-based instruments.
