Subject: [PATCH] Support geolocation in android webview

Summary:
Makes sure request for geolocation use in the webview is handled.
This solves issue #7609

Currently use of geolocation in webview fails silently, as the permission request is never received by the native app.

**Test plan (required)**

1. Create new project with webview
2. Add javascript for geolocation:
```javascript
navigator.geolocation.getCurrentPosition(function (position) {
  console.log('success', position)
}, function (error) {
  console.log('could not determine position', error)
})
```
3. Run code and assert geolocation permission is requested, resulting in success (or error) callback being called
Closes https://github.com/facebook/react-native/pull/8305
