[lldb] Refactor LLDB Breakpoint Event Notifications to centralize and eliminate code duplication (#164739)

### Summary

This PR refactors breakpoint event notification in LLDB to centralize
and eliminate code duplication. It creates a unified method in the
`Target` class for sending breakpoint change events. The new methods
check if listeners exist before broadcasting events
