Snapshot release with Test Gui for MSYS2 MinGW and macOS x64

macOS: use IORegistryEntryGetRegistryEntryID to resolve paths (#322)

With some device connection configurations,
the device paths become over 512 bytes (io_string_t max length)
which makes them unusable with current implementation.

Rather than using ServiceRegistry string path, use its ID,
which is uint64_t and easily serializable/deserializable into a string.
