Debugger: add a "don't ask again" checkbox to alerts

This allows, for example, to skip all the "get debug info" alerts when
starting a debug session. But it is a generic implementation and will
work for all "question" alerts in Debugger.

For now, the user choices are not saved, this could be done, but then we
need a way to access that setting later.

Fixes #14601
