Cleanup type symbol usage by consolidating to manage in one spot. This makes them easier to use as well by providing a single rollup of all the common type symbol's used throughout core.
API Level 30 is now included. Also the `native` namespace used for Android/Java typings no longer collides with integrations.
BREAKING CHANGE:
If you were using`native.Array` for any of your own custom plugin typings, you can switch them to `androidNative.Array`
BEFORE:
```
public writeAsync(path: string, bytes: native.Array<number>) ...
```
AFTER:
```
public writeAsync(path: string, bytes: androidNative.Array<number>) ...
```
The idea is for views to handle sepecial case themselves.
I realised that android.widget.Button was materialized even if you were not using it because there was a test for instanceof in the background handling. Now the special background handling is done in Button and ActionBar
