Aims for more consistent MIDI support across Windows, MacOS, Linux and to provide a base for adding MIDI drivers for other platforms. Reworks the MIDIDriverALSAMidi MIDI parsing implementation as a platform independent version in MIDIDriver::Parser. Uses MIDIDriver::Parser to provide running status support in MacOS MIDIDriverCoreMidi. Collects connected input names at open, ensuring devices indices reported in events match names in array returned from get_connected_inputs. Fixes #77035. Fixes #79811.
