Since no threads are waiting for the FIFO and we do not need any k_fifo
features, we can just use slist.
Some notifications (caused by interrupts), especially "VBUS ready", can
be triggered very quickly right after UDC initialization if the USB

configuration, messsage publishing work can be executed before the
context is marked as initialized. Use delayed work to reschedule
publishing when the context is not initialized.

USB High-Speed devices must be able to operate at both High-Speed and
Full-Speed. The USB specification allows the device to have different
configurations depending on connection speed. Modify the API to reflect
USB Specification requirements on what can (e.g. configurations) and
what cannot (e.g. VID, PID) be speed dependent.
While the class configurations for different speeds are completely
independent, the actual class instances are shared between operating
speeds (because only one speed can be active at a time). Classes are
free to provide different number of interfaces and/or endpoints for
different speeds. The endpoints are assigned for all operating speeds
during initialization.

For specification-compliant high-speed support, we need to support
device quilifiers and other-speed-configuration descriptor requests. We
also need to store different configurations of the class/function
descriptors, which typically only affect the endpoint descriptors. With
this change, the stack expects class/function descriptors to be passed
as an array of struct usb_desc_header pointers to e.g. interface,
interface-specific, and endpoint descriptors, with the last element of
the array pointing to a nil descriptor. And also passed for a specific
speed, for now we support full and high speed configurations.
During instantiation, the class/function implementation must choose the
correct configuration in the full-speed and high-speed descriptor sets
for values such as maximum packet size and bInterval values of interrupt
and isochronous endpoints.
During initialization, the stack reads the highest speed supported by
the controller and uses it to get the appropriate descriptors set
from the instance. If the controller supports only full speed, the stack
configures the class/function descriptor for full speed only, if the
controller supports high speed, the stack configures the descriptors for
high speed only, and a class/function must update the full speed
descriptor during the init callback processing.
During device operation, the class/function implementation must check
the actual speed of the device and use the correct configuration, such
as the endpoint address or maximum packet size.

The implementation uses the system workqueue and a callback provided
and registered by the application. The application callback is called in
the context of the workqueue. Notification messages are stored in a
queue and delivered to the callback in sequence.
We cannot call application callback directly from the USB device stack
thread because the behavior of arbitrary code provided by the
application is unpredictable, and we do not want it to be executed in
the same context where all events from the device controller are
handled.
Nor can we use the ZBUS subsystem directly. ZBUS offloads responsibility
for defined behavior to the observers and application, and does not
provide any way for the publisher to enforce defined behavior and
execution context.
ZBUS listener would be called from the USB thread context and is not
acceptable. ZBUS subscriber does not provide delivery guarantee and
cached message can be overwritten. ZBUS message subscriber has
cumbersome global configuration and buffers that are too complicated to
handle from USB configuration, and even if we would use it, defined
behavior is not possible because of how listener and subscriber are
handled.
