feat(browser): inAppIntegration which uses debugId filenames to determine in_app on stack frames

[timfish]

Currently in the browser, all stack frames are marked with in_app: true which makes it difficult to determine if the error originated from user code or elsewhere.

If we have debugIds we can assume that these filenames are the users app code and everything else is not.

This PR adds the inAppIntegration that uses the filenames associated with debugIds to determine in_app. It adds a getFilenameDebugIdMap function which replaces identical code in 3 other places.
