[Debug] Rename DebugDescription fallback property to lldbDescription (#75289) - **Explanation**: From feedback, replace the name `_debugDescription`, which was confusing because of the underscore, with `lldbDescription`. - **Scope**: This will not break existing code. Any existing uses of `_debugDescription` would see that the debugger does not produce a summary string, but would still display all fields/children of a value. - **Original PRs**: https://github.com/swiftlang/swift/pull/75305 - **Risk**: Early adopters of `_debugDescription` will not see their summary string shown. - **Testing**: Swift tests, CI. - **Reviewers**: @hborla, @stephentyrone, @DougGregor
