795d9402 - [lldb][cmake] Fix standalone Xcode build header staging (#177033)

[lldb][cmake] Fix standalone Xcode build header staging (#177033) The LLDB standalone build using Xcode fails because the staging directory custom command output is attached to multiple liblldb-stage-header-* targets, but none of these targets depend on each other. Xcode's new build system doesn't allow this. This creates a new target `liblldb-header-staging-dir` that depends on the staging directory creation, and makes all header staging targets depend on it instead of directly depending on the directory in their custom commands. This ensures all targets share a common dependency, satisfying Xcode's build system requirements.
