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.

This patch also fixes two similar strlen() occurrences in the same source file.

ERROR 8192: strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [/var/www/html/phorge/phorge/src/applications/almanac/management/AlmanacManagementRegisterWorkflow.php:41]

Run ../phorge/bin/almanac register: Get no strlen() error anymore but only expected output Usage Exception: Specify a device with --device.
