feat: make nativescript identify as browser in angular (#136)

This enables all the browser features like `@defer`, `afterRender` and `afterNextRender`, which are integral parts of new updates (including the angular router in the future)

BREAKING CHANGES:

Identifying as browser can have minor impact on existing libraries that use that to manipulate the DOM. So far, the usage inside angular itself is minimal enough that it shouldn't impact apps other than enabling previously mentioned features.
