Add warning if carb quantity exceeds warning limit (#1873)

* Use LoopConstants for maxmaxCarbEntryQuantity instead of adding a constant in CarbEntryViewController

* Not quite working yet - need help with warning portion, see also LoopKit change

* Carb quantity validation: add warning, modify messages

* move show warning to ValidateInput function

* Update large meal warning with two actions

* Update comment
