Updated error translation logic.
This CL changes several aspects of our error translation code:
- Moves the actual translation process to |-loadErrorInNativeView:|.
This allows the logic in |-handleLoadError:inMainFrame:| to correctly
differentiate between webview-generated errors and errors originating
from the net stack.
- Changes |NetErrorFromError()| to translate the ultimate underlying
error rather than the top-level error, and appends the translated
error to the end of the passed-in error's underlying error chain.
- Created |GetUltimateUnderlyingErrorForError()|, which iterates through
the underlying error chain to find the original error.
