rPe65ac7b8800d: Fix PHP 8.1 "strlen(null)" exceptions which block rendering the Conpherence page

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 T15304

Test Plan

Applied these four changes (on top of D25144, D25145, D25146, D25147, D25150,
D25151, D25152, D25153) and /conpherence/ page finally rendered in web browser.

I tested this locally without any explosion related to alien checks of phutil_nonempty_string(). I was able to use Conpherence, search stuff, search full text, etc. Thanks
