chip/stm32/usb: Replace reset handler by generic event handler
Some USB interface handlers need to know when USB has been successfully resumed after a wake event. For example, this is useful so that HID keyboard can send the events at the right time. BRANCH=none BUG=b:35775048 TEST=Using USB HID keyboard patches to queue keys in a FIFO: After USB autosuspends, press a single key and hold it. Without this patch the endpoint data only gets reloaded on the _next_ event. TEST=On hammer, I2C passthrough still works.
