Set the value of the control to value.
If onlySelf is true, this change will only affect the validation of
this Control and not its parent component. If emitEvent is true,
this change will cause a valueChanges event on the Control to be
emitted. Both of these options default to false.
If emitModelToViewChange is true, the view will be notified about the
new value via an onChange event. This is the default behavior if
emitModelToViewChange is not specified.
