[12.x] Ability to perform higher order static calls on collection items

[daniser]

This PR adds ability to perform higher order static calls on collection items (class names).

Example usage scenario:

interface Handler
{
    public static function satisfies($condition): bool;
}

class HandlerFactory
{
    protected Collection $handlers;

    /**
     * @param  list<class-string<Handler>>  $handlers
     */
    public function construct(array $handlers) // ❤️giveConfig
    {
        $this->handlers = collect($handlers);
    }

    public function make($condition): Handler
    {
        $handler = $this->handlers->first->satisfies($condition) ?? FallbackHandler::class;

        return new $handler;
    }
}
