rP81653abb5440: Fix PHP 8.1 "strlen(null)" exceptions adding an OAuth provider

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.

ERROR 8192: strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [/var/www/html/phorge/phorge/src/applications/auth/provider/PhabricatorOAuth2AuthProvider.php:140]

ERROR 8192: strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [/var/www/html/phorge/phorge/src/applications/auth/provider/PhabricatorOAuth2AuthProvider.php:155]

ERROR 8192: strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [/var/www/html/phorge/phorge/src/applications/auth/provider/PhabricatorOAuth2AuthProvider.php:165]

Closes T15786

If we find 10 minutes, let's test this on every provider, as last time it gave us a little surprise on one of them

I checked this with two or three providers - it's used in a common string for all OAuth providers and refers to an ID, Secret, or Property note.

But if we ever ran into some surprise here (e.g. getting an integer instead of a string) then we'd know to change phutil_nonempty_string into phutil_nonempty_scalar? :)

Thank you for testing. I think this looks good. In the one case that the old var is used it’s rendered as a string in pht so string assumption seems okay here.

I’m good with this if @valerio.bozzolan is
