Fix PHP 8.1 "strlen(null)" exceptions editing a form when custom field of type Date exists

Browse source 
Summary:
`strlen()` was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts `phutil_nonempty_scalar()` as a replacement when both string and integers could be passed as a value like here.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_scalar() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

Also fix similar warning for `ctype_digit(): Argument of type null will be interpreted as string in the future` by checking for `null` first.

```

Closes T15601

Test Plan: After applying these three changes and creating a custom field with `"type": "date"` under `/config/edit/maniphest.custom-field-definitions/`, the website `/transactions/editengine/maniphest.task/view/5/` renders correctly in the browser, showing "This is a preview of the current form configuration."
