[JS] Fix several issues found in pdf in #13269

- app.alert and few other function can use an object as parameter ({cMsg: ...});
  - support app.alert with a question and a yes/no answer;
  - update field siblings when one is changed in an action;
  - stop calculation if calculate is set to false in the middle of calculations;
  - get a boolean for checkboxes when they've been set through annotationStorage instead of a string.
