Prepare for removal of `parseErrorStack` and `symbolicateStackTrace` from RN Public APIs

[krystofwoldrich]

Description

As mentioned in facebook/react-native#51737 (PR fixing TS types for the mentioned functions) and react-native-community/discussions-and-proposals#894 (RFC about removing deep RN Core imports).

• fix(types): Devtools.d.ts facebook/react-native#51737
• RFC0894: Removing deep imports from react-native react-native-community/discussions-and-proposals#894

Proposal

• parseErrorStack should be easily replaced by Sentry Core SDK parsing functions.

• symbolicateStackTrace makes a network request to the /symbolicate endpoint, this can be replaced by a custom __sentry/symbolicate
