rPd25d630fe5dd: PHP 8.2: fixes for strlen() not accepting NULL anymore, part 1

Summary

This change avoids some unnecessary uses of the strlen() function,
actually fixing some deprecation warnings in PHP 8.2.

In short, this is the suggested universal replace:

-if(strlen($v))
+if(phutil_nonempty_string($v))

And, if you know PHP, this is also another adoptable replace, but
only for cases where you are sure that the string "0" is not useful:

-if(strlen($v))
+if($v))

As usual the optimal solution depends on the contest.

Other similar patches will probably follow.

Closes T15222
Ref T15190

Test Plan

for the first time in my life, with this change, the unit tests are passed in PHP 8.2
check with your big eyes that there are no obvious typos

I'm not convinced that a host named 0 is invalid, but fine.
