Fix PHP 8.1 "strlen(null)" exception which blocks creating a project with an empty Description field

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_stringlike()` as a replacement for string-alike variables.

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

Closes first half of T15331

Test Plan: Applied these two changes (one in Arcanist, one in Phorge). Project with empty Description field was created and `/project/view/projectid/` rendered in web browser.
