ref(replay): Export WINDOW within Replay instead of importing it from Browser (#6386)

In preparation to generating CDN bundles, this change copies the `WINDOW` constant declaration from `@sentry/browser` to the Replay package and updates the imports to use the package-internal version of `WINDOW`. This has two advantages:

* When building CDN bundles, we don't bundle contents from `@sentry/browser` anymore. This previously caused the generated bundles to not work correctly and it unnecessarily increased bundle size
* By not importing anything from `@sentry/browser` we avoid a circular dependency one we export the Replay integration from the Browser SDK.
