Fixed Deprecated exception when using trim filter in PHP 8.1

@XF Bug Bot, I should point out that XF\Template\Templater::fnTrim also sometimes throws this message because the method does not ensure that the incoming template text in $str has been cast to string (occasionally a {$...|raw} may not have been passed, may be an integer, etc).

The new method should be:
Code:
	public function fnTrim($templater, &$escape, $str, $charlist = " \t\n\r\0\x0B")
	{
		$str = (string)$str;
		return trim($str, $charlist);
	}
Also, in XF\Template\Compiler\Trim, it should call $templater->fnTrim and not trim directly, or if the escaping is a problem, XF\Templater\Compiler\Trim should also make sure that $valueHtml is cast:
Code:
return "trim((string){$valueHtml})";

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.2.9).

Improve PHP 8.1 compatibility in template trim tag/function
There may be a delay before changes are rolled out to the XenForo Community.
