Move the network buffer header file from zephyr/net/buf.h to
zephyr/net_buf.h as the implementation now lives outside of the networking
subsystem.
Add (deprecated) zephyr/net/buf.h header to maintain compatibility with old
file path.

audio_receive_cb is only used by headphones and headset, it is unused in
microphone-only configurations. Gate compilation based on the device
tree.

Effectively, this option changes code triple in device descriptor.
Although the name is misleading, renaming it would again lead
to negative user experiences. Instead, clarify what the option does
and always select it where it is required.

Every USB device must buffer isochronous data for at least 1 frame in
order to remove packet jitter within a frame. USB Specification Revision
2.0 describes necessary buffering in 5.12.5 Data Prebuffering. USB Audio
1.0 specification mentions buffering in 3.4 Inter Channel Synchronization.
Set bDelay to 1 instead of 0, because bDelay 1 is both the minimum
allowed value and matches the actual device behavior.

Pass result of usb_transfer() as return value to the user,
and allow user to react accordingly, e.g. release net_buf on error.

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Until now the whole USB device stack code is located
in the top subsys/usb directory. Move it to own directory
in preparation for upcoming extension and rework of USB support.
