[lldb] Deprecate SBBreakpoint::AddName in favor of AddNameWithErrorHandling (#71228)

AddName gives no feedback other than if it succeeded whereas
AddNameWithErrorHandling gives you back an SBError object. I would like
to mark AddName as deprecated and direct folks to use
AddNameWithErorrHandling instead.
