FR-14187 - support standalone components

[yuvalotem1]

Create provideFrontegg function to provide all frontegg providers in the root of the application.
using this function will look like this -

// inside app.config.ts created by angular/cli 17
import { ApplicationConfig } from '@angular/core';
import { provideRouter } from '@angular/router';
import { routes } from './app.routes';
import { provideFrontegg } from '@frontegg/angular';

const fronteggConfig = {
  contextOptions: {
    baseUrl: 'https://yuvaldev.stg.frontegg.com',
  }
}

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideFrontegg(fronteggConfig),
  ],
};

The main gap is currently using AuthorizedContentDirective won't come out of the box and will require extra configuration by adding FronteggAppModule to the app.module.ts components imports
