[RFC PATCH 09/14] monitor/qmp: Explicit we ignore few QEMUChrEvent in IOEventHandler

[Philippe Mathieu-Daudé]

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      monitor/qmp.o
  monitor/qmp.c: In function ‘monitor_qmp_event’:
  monitor/qmp.c:345:5: error: enumeration value ‘CHR_EVENT_BREAK’ not handled 
in switch [-Werror=switch]
    345 |     switch (event) {
        |     ^~~~~~
  monitor/qmp.c:345:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not handled 
in switch [-Werror=switch]
  monitor/qmp.c:345:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ not handled 
in switch [-Werror=switch]
  cc1: all warnings being treated as errors
