DRAFT angular: AngularContext support

[PatrickJS]

In order to support Angular we need to add the missing feature in Angular which is <AngularContext>. Which will allow us to hook into the injector hierarchy for <App> with either ReflectInjector or StaticInjector

// `injector` is optional
<AngularContext injector={this.injector}>
  <App>
</AngularContext>

any code within <App> will work correctly without any refactors needed since at the end of the day we're looking for a key walking up the injector context.

Mitosis can compile the code correctly and it will be up to the dev to either create the injector context correctly or we can let them generate the NgModule/AngularContext

We can also rename this to <AngularInjector> and useInjector and alias it to useContext. We will support useInjector if an react app is getting the ng injector if react is rendered in an angular app

[PatrickJS]

we need to change methods based on which angular version they're using. In angular 14 we can use inject which will make the code simple

Adoption usually takes a while, it seems safe to target Angular 14 and up as that will likely no longer be the latest version when Mitosis has a big enough user base for there to be lots of demand for “not the latest Angular” support
