debugger(posix): Refactor LibDebugger POSIX engine: rename, namespace update, API cleanup

- Renamed `IDebuggerEngine.h` → `POSIX.h` and `DebuggerEnginePOSIX.cc` → `POSIX.cc`
- Moved `IDebuggerEngine` class into `LibDebugger::POSIX` namespace and renamed it to `Debugger`
- Simplified method names:
  - `SetBreakpoint` → `Break`
  - `ContinueExecution` → `Continue`
- Replaced generic return codes with `EXIT_SUCCESS` / `EXIT_FAILURE`
- Updated includes and symbol usage to reflect changes across the codebase
