rPe5caf4333e5e: Fix PHP 8.1 "strlen(null)" exception which blocks creating a blog post

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 T15357

Test Plan

Applied this change and created blog post at /phame/post/view/3/blogpost/ rendered in web browser.

70–72	✅ I verified the above line The line was split so to make the linter happy. I verified that `$blog->getDomain()` is never a `PhutilURI` but always is null or a string provided by the user. The function `phutil_nonempty_string()` will report any alien type, and that is OK.
