AGOS: Fix Accolade MIDI Driver Compilation Breakage

These were broken by the last PR merge which included a cpp file in a
way which will not build reliably. This splits the Accolade MIDI driver
structure definitions into headers allowing these to be included
instead.

Also, minor cleanup by removal of unused header includes.
