Add wxCMD_LINE_SWITCH_NEGATABLE which allows to use a dash after a command
line switch to inverse its meaning (i.e. use "/X-" form). Also add new
wxCmdLineParser::FoundSwitch() allowing to check for whether the switch was
specified in normal or negated form.
Closes#11643.

Use "wxWindows licence" and not "wxWidgets licence" (the latter doesn't
