Convert Angular components to use standalone api-s

[eneajaho]

Standalone api-s are becoming stable in v15, so it would be great if the components that we have can be converted to standalone.

Hi, I would like to implement that option, but I'd like to know if it should be a simple change in current templates, or another option to choose an example (Angular standalone).

How should be done?

I'd just change the current impl

It's in progress in this PR I think: #245

That's not exactly what I did. I made another angular option called "Angular Renaissance" with every new feature from v14 to now, showing signals (with signal based components too), provideXxx functions, etc.
Right now, I have an issue when building the app. I haven't been able to fix it yet.
