usb: device: remove USB H4 Bluetooth function and sample 

The Bluetooth HCI USB transport layer implementation is provided by
"subsys/usb/device/class/bluetooth.c". The USB H4 Bluetooth function
implements a non-standard transport layer. There is no known host-side
equivalent that uses this protocol.

Note that the H4 protocol functionality is also provided by the
"subsys/usb/device/class/bluetooth.c".

Since that there are no real USB H4 Bluetooth users, remove the
implementation and sample without deprecation.

.. zephyr:code-sample:: bluetooth_hci_usb_h4

   :name: HCI H4 over USB

   :relevant-api: hci_raw bluetooth _usb_device_core_api usbd_api



   Turn a Zephyr board into a USB H4 Bluetooth dongle (Linux/BlueZ only).



Overview

********



Make a USB H4 Bluetooth dongle out of Zephyr. Requires USB device support from

the board it runs on (e.g. :ref:`nrf52840dk_nrf52840` supports both Bluetooth LE and

USB).



Requirements

************



* Bluetooth stack running on the host (e.g. BlueZ)

* A board with Bluetooth and USB support in Zephyr



Building and Running

********************

This sample can be found under :zephyr_file:`samples/bluetooth/hci_usb_h4` in

the Zephyr tree.



See :zephyr:code-sample-category:`bluetooth` samples for details.
