Summary0001115: Support Windows 10 UWP MIDI API
Description

The new UWP MIDI API in Windows 10 supports features such MIDI over Bluetooth and being able to open a port from more than one application at the same time.
A sensible approach might be to use this C wrapper, which allows the API to be used in a plain Win32 application when available, and fall back to WinMM if Windows 10 is not available: https://github.com/stammen/winrtmidi

Support for RtMidi was also merged recently: https://github.com/thestk/rtmidi/pull/299

RtMidi has been updated to v6.0.0 in our repository, which means that UWP support can now be enabled for testing purposes.

An odd side effect of turning on UWP MIDI support in RtMidi makes the ASSERT(oleinit != FALSE); assertion in CTrackApp::InitInstanceEarly fire. Ignoring that assertion, it can be observed that e.g. MFC falls back to using the old-style file dialogs.

It appears that output port names (but not input port names, mysteriously!) from devices that only implement the MM API are butchered when they are exposed through the UWP API. RtMidi tries to work around this but it doesn't always succeed. This is definitely one reason for not completely replacing MM with UWP when both are available.
