NotifTroubleshootingScreen: Add Android manufacturer/model info to re…

…port

This could provide useful context, e.g., to diagnose issues like
issue #4074, "Some device vendors break notifications".

Unfortunately, in my test using an emulated Pixel XL (results
recorded in jsdoc), none of these three fields actually had anything
like "Pixel XL" in it. Possibly we could get that from something
like Android's `Build.PRODUCT`, documented as "the name of the
overall product":
  https://developer.android.com/reference/android/os/Build#PRODUCT
but React Native's Platform.constants doesn't expose that value or
any other that seems likely, and we have more urgent tasks than
plumbing things through React Native (like
<https://github.com/zulip/zulip-flutter>).
