Do not add this folder to the include path when this component is not
enabled. As that creates noise and slows down builds.

Passing a USB-MIDI device in a ump stream responder configuration,
as obtained from the device tree with DEVICE_DT_GET(), was wrongly
casting is from const struct device* to void*, hence removing the const
pointer attribute.
This incorrectness introduces some compilation issue. Let's therefore
make the device pointer constant in ump_stream_responder_cfg, and
add a macro to make the proper typecast consistently. Finally, adapt the
corresponding samples to use that new macro.

Add a new top-level, transport independent library to respond to UMP Stream
Discovery messages. This allows MIDI2.0 clients to discover UMP endpoints
hosted on Zephyr over the UMP protocol.
The endpoint specification can be gathered from the device tree, so that
the same information used to generate USB descriptors in usb-midi2.0
can be delivered over UMP Stream.
