Summary: Remove tests that only test legacy component stack behavior. The 'stack' tests provide equivalent coverage for all scenarios. Legacy component stacks used a custom React string format (`\n in ComponentName (at filename.js:123)`) that was not symbolicated. The modern 'stack' format uses native JS Error stack frames that get properly symbolicated. This is the first step in removing `componentStackType` from LogBox entirely. The legacy parsing logic will be removed in a follow-up diff. Reviewed By: vzaidman Differential Revision: D90888272
Summary: All component stacks now use the native JS Error stack frame format which gets properly symbolicated. This removes the legacy/stack distinction since the legacy format (custom React string format) is no longer used. After this change, all component stacks will be symbolicated, improving the debugging experience. Reviewed By: vzaidman Differential Revision: D90888223
Summary: LogBox was doing a wasteful round-trip conversion: parseComponentStack converted Stack → ComponentStack, stored it that way, then convertComponentStackToStack converted it back every time it was used. This eliminates the unnecessary conversion by storing componentStack as Stack directly from the start. The ComponentStack type is removed entirely since it's no longer needed. Also consolidates duplicate helper functions in LogBoxLog-test.js by removing createStackForComponentStack and createComponentStack, keeping only the createStack helper.
