rPd8d45d343ed4: Fix PHP 8.1 "strlen(null)" exceptions which block rendering the Conduit 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 T15307

Test Plan

Applied these two changes (on top D25144, D25145, D25146, D25147, D25150,
D25151, D25152, D25153, D25154 locally applied) and /conduit/ finally
rendered in web browser. Also the page /conduit/query/.

src/applications/conduit/query/PhabricatorConduitSearchEngine.php
42	✅ I logged the value of `$contains` in /conduit/query/ and its domain seems to be always NULL or a string. Alien values will be reported by `phutil_nonempty_string()` and that is OK.
src/view/phui/PHUIObjectItemView.php
877	✅ I logged the value of `$label` in 50+ pages and its domain seems to be always NULL or a string. Alien values will be reported by `phutil_nonempty_string()` and that is OK.
