Migrate samples to standalone components

[jackofdiamond5]

Description

We want to update our samples project to use standalone components instead of NgModules. All components should be standalone and should import their template dependencies as expected, the routing should be reworked, no NgModule-s should exist in the project. Bootstrapping of the project should begin on the AppComponent level, there may be changes to global providers as well.

A possible reference point could be the top three commits made on this branch migrate-to-standalone-components. An additional reference point is the igniteui-angular repository since it has already been updated to use standalone components.
