use getArg(name, position) over getArgs() when possible on CallLike

[samsonasik]

The CallLike has getArg(name, position) so it can get when it uses named argument match, or by position match.

• feat: add CallLike::getArg() method nikic/PHP-Parser#1089

This on specific target argument, can reduce named argument match check, or first class callable, as checked early return null there.

Linked possible issue with internal php-parser:
