Introduce new USB Mass Storage Bulk-Only Transport implementation
written from scratch. Main goal behind new implementation was to
separate USB and SCSI parts as clearly as possible.
Limited set of SCSI disk commands is implemented in separate source code
file that is internal to USB device stack. While it should be possible
to use the SCSI implementation by other components there is currently no
other user besides USB MSC and therefore SCSI header is kept private.

Use a consistent nil_desc name for the descriptor that
terminates a class (function) descriptor.

Add USB device class API to notify class instances that an endpoint
has been halted or cleared due to a feature request.

Use proper format for size_t type eliminating warnings of type:
...
error: format '%u' expects argument of type 'unsigned int', but
argument 2 has type 'size_t' {aka 'long unsigned int'}
[-Werror=format=]

Add Bluetooth HCI USB transport layer implementation for the new
experimental USB device support based on the existing implementation
subsys/usb/device/class/bluetooth.c.
This implementation, unlike existing one, contains the interface
descriptors for isochronous endpoints. Since we do not support voice
channels, these are just there to avoid issues with Linux kernel btusb
driver when this implementation is part of a composite configuration.

USB stack did leak memory on every SET ADDRESS request. UDC control
allocator could cope with up to 13 leaked allocations. Therefore,
issuing bus reset 13 times in a row (in addition to automatic reset
after connecting the USB cable) was enough to exhaust memory and
thus drive USB stack inoperable.

The name and wording used in template can be misleading.
Use more accurate word instance instead of device since
an implementation does not necessarily have to implement
a device (in the sense of Zephyr device model), and if it
does then devicetree should be used to describe number of
instances as in the case of CDC ACM implementation.

Clean up occurrences of "#if IS_ENABLED(CONFIG_FOO)" an replace
with classical "#if defined(CONFIG_FOO)".

Add experimental CDC ACM implementation for new USB device stack.
It currently implements only UART IRQ API support and is WIP.

The device supprt brings support for multiple stack instances,
multiple configuration, asynchronous transfer model, ability to
change most of the properties of a device at runtime and
the composition of configuration and classes at runtime.
The stack requires new UDC driver API and is not compatible
with old driver API (usb_dc_). The classes (functions) of old
(current) USB device stack cannot be used with new ones and must
be ported.
