[NFR]: Replace regexp in the router with arrays for extra performance

[diplopito]

Is your feature request related to a problem? Please describe.
Current MVC routers have the problem that when there are many paths, there is a performance penalty due to the use of regular expressions.

Describe the solution you'd like
Replace the use of regular expressions with arrays

Describe alternatives you've considered
Declare a constant array with paths, a simple example:

\* PATHS contains url paths as key, controllers and actions are defined 
in a value array, i.e. ['path'] => [controller, action] */
const PATHS = [
    '/cont2/show'  => ['SecondController',  'show'],
    '/cont4/delete' => ['FourthController', 'delete'],
    // ....
];

function urlPath()
    {
        $uri = new Uri($_SERVER['REQUEST_URI']);
        $parts = explode('/', $uri->getPath());
        $controller = $parts[1] ?? "index";
        $action = $parts[2] ?? "indexAction";
        return "/$controller/$action";
        ];
    }

Then, to match and execute the routes:

try {
       $path = urlPath();
       $controller= self::PATHS[$path][0];
       $action=  self::PATHS[$path][1];

       $mvc = new $controller();
       $mvc->$action();
} catch {\Exception $e) {
       // Path not matched, throw an exception
}

The increase of performance is notorius. Furthermore, it can be extra optimized by splitting PATHS into module arrays to create microcollections, it can process variables (with regex), etc. In this way, Phalcon could handle many paths with Phalcon speed and performance!
