Add feature to switch to cpp variables for objc executable action

With linking info having migrated to CcInfo, we no longer need the custom objc
variables for linking actions.  This change adds support for objc link action to
emit cpp link variables.  This requires changes to the crosstool as well, so we
add a feature "use_cpp_variables_for_objc_executable" to control whether to use
it.  Once we have migrated all the crosstools, we can delete support for the
objc linking variables.

A nice benefit of switching to cpp variables is that we get the ability
eliminate archive actions for free (for linkers that support start/end_lib).
