Fix PHP 8.1 "strlen(null)" exceptions which block rendering page to import ICS calendar file

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_string()` as a replacement.

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

Closes T15362

Test Plan: Applied these two changes and `/calendar/import/edit/` correctly rendered the "Create Import" page in the web browser, with the expected error about the missing ICS file (instead of an exception stacktrace).
