  [OpenMP] Use ext linkage for kernels handles and globals handles keep linkage

Host handles are now emmitted with external linkage to clash if two
kernels with the same name are registered. This could have happen right
now and silently corrupt the program, but it can happen more easily once
we allow users to name their kernels.

In the same patch we make global variable handles retain the linkage of
the global variable, forcing clashes for external ones and continue to
support weak use cases.
