React-native iOS stack trace needs symbolication

[BethanyBerkowitz]

See #1069 (comment)

In the iosUtils.ts file, the backtrace generated does not match the BacktraceFrame type. This code parses the localizedDescription from the iOS error into something resembling a Honeybadger backtrace, however it doesn't make a lot of sense when passed in because the localizedDescription is not symbolicated... it doesn't contain lines or columns, or even file names. Instead it has a memory address, which needs to be translated.

This document from Andrey provides useful background on iOS symbolication.

I'm not sure how this was intended to work, but it may have to do with https://github.com/honeybadger-io/react-native-internal/tree/main/resolve_ios_backtrace.
