The 'if condition' in usb_handle_control_transfer is diffcult
to understand. So I rewrite another version.

Add new status event indicating an interface has been selected.
Interface and its endpoint(s) are enabled.

The transfer API provides 'high' level functions to manage sending and
reception of USB data. A USB (class) driver has to register the generic
usb_transfer_ep_callback as endpoint status callback in order to use
the API.
With this API, the class driver does not need to take care of low-level
usb transfer management (packet splitting, ZLP, synchronization...).
The usb_transfer methods will split transfer into multiple transactions
depending endpoint max size and controller capabilities.
Once the transfer is completed, class driver is notified by a callback.
The usb_transfer method can be executed in IRQ/atomic context.
A usb_transfer synchronous helper exists which block-waits until
transfer completion.
In write case, a transfer is complete when all data has been sent.
In read case, a transfer is complete when the exact amount of data
requested has been received or if a short-pkt (including ZLP) is
received.
transfer methods are thread-safe.
A transfer can be cancelled at any time.

At the moment CONFIG_SYS_LOG_USB_LEVEL name does not specify that this
is log level for the Device Stack. Make it clear renaming to the
proper name.

Move logging out of misc/ to its own subsystem. Anything related to
logging and any new logging features or backends could be added here
instead of the generic location in misc/ which is overcrowded with
options that are not related to eachother.

USB class drivers may need to offload some work from
upcall interrupt context to a background fiber. This
requires some way to defer taking more data from host
till the offloaded work completes. Two APIs are added to
achieve this.
Further USB class drivers sometimes need to set STALL condition
on end-points to signal errors to host.These too are
added.
