The Chardev events are listed in the QEMUChrEvent enum. To be
able to use this enum in the IOEventHandler typedef, we need to
explicit when frontends ignore some events, to silent GCC the
following warnings:

    CC      hw/usb/redirect.o
  hw/usb/redirect.c: In function ‘usbredir_chardev_event’:
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_BREAK’ not handled in switch [-Werror=switch]
   1361 |     switch (event) {
        |     ^~~~~~
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not handled in switch [-Werror=switch]
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ not handled in switch [-Werror=switch]
  cc1: all warnings being treated as errors
