Michael Gregorius d3d710e0ad Remove identical calls to InstrumentTrack::processAudioBuffer 
Remove identical calls to `InstrumentTrack::processAudioBuffer` which appear in the overridden implementations of `Instrument::play` and `Instrument::playNotes`. Instead the call to `processAudioBuffer` has been moved into `InstrumentPlayHandle::play` and `InstrumentTrack::playNote`. These two methods call the aforementioned methods of `Instrument`. Especially in the case of `InstrumentTrack::playNote` the previous implementation resulted in some unncessary "ping pong" where `InstrumentTrack` called a method on an `Instrument` which then in turn called a method on `InstrumentTrack`. And this was done in almost every instrument.

In `InstrumentTrack::playNote` an additional check was added which only calls `processAudioBuffer` if the buffer is not `nullptr`. The reason is that under certain circumstances `PlayHandle::doProcessing` calls the `play` method by explicitly passing a `nullptr` as the buffer. This behavior was added with commit 7bc97f5d5b. Because it is unknown if this was done for some side effects the code was adjusted so that it behaves identical in this case.

Move the complex implementation for `InstrumentPlayHandle::play` and `InstrumentPlayHandle::isFromTrack` into the cpp file and optimize the includes.
