T15064: Make Phorge compatible with PHP 8.1/8.2/8.3/8.4
T15190: PHP 8.1: strlen() and other scalar-only functions do not accept NULL anymore - understand fix strategies

Summary

This is a fix for PHP 8.1 deprecation of strlen(NULL), for these Phorge components:

src/view
src/infrastructure (partial, needs more patches)

The strlen() was used in Phabricator to check if a generic value was a non-empty string.
For this reason, Phorge adopts phutil_nonempty_string() that checks that.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If your phutil_nonempty_string() throws an exception, just
report it to Phorge to evaluate and fix together that specific corner case.

As usual, the risk of this change is that exceptions may occur due to
really weird stuff coming in as input. In any case, if it happens,
it must be evaluated on a case-by-case basis, because in this case,
the previously present code (strlen) didn't make sense anyway either.

22	That above check was introduced by this commit: rP96ae4ba13acb: PHP 8.1: fixes for strlen() not accepting NULL anymore, part 2 But it's too much strict. I have double-checked and this deserves more inline documentation. See on the right. I just added some comments, and a strong default.
47	Also this method ↓ deserved an inline comment to show that it can return mixed stuff.
140	IMPORTANT: this cannot be used as-is, since getDownload() returns mixed stuff by design it seems.

src/infrastructure/log/PhabricatorSSHLog.php
38	This replacement has sense since everything from `getenv()` should be a string and we should report otherwise.
src/infrastructure/management/PhabricatorManagementWorkflow.php
17	This check has sense since then we use `strtotime($time)` so we really want a string, and we should report alien stuff.
src/infrastructure/query/policy/PhabricatorCursorPagedPolicyAwareQuery.php
2452	This check has sense since then we want to count length in bytes, so a string is necessary.
src/infrastructure/ssh/PhabricatorSSHWorkflow.php
104	This check has sense since we want a string and we want to report alien values from `getenv()`.
