Fix ForbidCheckedExceptionInCallableRule for PHPStan fiber processing

Refactor the rule to use Scope::getFunctionCallStackWithParameters()
instead of relying on node processing order, which broke with PHPStan's
fiber-based processing.

The new implementation:
- Uses scope's call stack to determine if callable is immediately invoked
- Handles IIFEs (immediately invoked function expressions) separately
- Properly resolves named arguments to correct parameters

Note: There's a PHPStan bug with named argument parameter matching
that affects edge cases. Fix: phpstan/phpstan-src#4791
