Use sentry_options_add_view_hierarchy to attach view hierarchy to native crashes

[bruno-garcia]

The Sentry native SDK added a new API to attach view hierarchies:

https://github.com/getsentry/sentry-native/pull/1191

This should allow not only non-fatal errors from having the view hierarchy sent to Sentry but also crashes, assuming we're able to get the view hierarchy in those cases.
