Code Review
This pull request refactors the iOS LLDB debugging logic by removing the Xcode dependency from IOSCoreDeviceLauncher and LLDB. It simplifies log handling by removing breakpoint-specific suppression and updates the breakpoint detection mechanism to use a specific string pattern. Additionally, it disables LLDB's asynchronous mode to address breakpoint rearming issues and updates integration tests for code signing verification. Feedback suggests enhancing the breakpoint detection regex to handle plural locations and improving the clarity of the associated documentation and variable naming.
