Description

Fix PHP 8.1 "strlen(null)" exceptions blocking account registration with custom OAuth provider after redirect

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.

EXCEPTION: (RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261]

Closes T15590

Test Plan:

Phorge user account registration page "Create a New Account" at /auth/register/abcdefghijklmnopqrstuvwxyz0123456/ now renders as expected, instead of displaying errors only.
