usb: gadget: Introduce handle_interrupts ops to USB_GADGET_GENERIC uclass

Introduce .ops for USB_GADGET_GENERIC uclass. The first new ops is
.handle_interrupts which must be implemented by DM capable USB gadget
controller drivers and must implement interrupt handling similar to
dm_usb_gadget_handle_interrupts(). This patch currently provides weak
dm_usb_gadget_handle_interrupts() implementation which is overridden by
the drivers, but this will be removed once conversion to handle_interrupts
callback is complete.
