[openmp][amdgpu] Tear down amdgpu plugin accurately
Moves DeviceInfo global to heap to accurately control lifetime.
Moves calls from libomptarget to deinit_plugin later, plugins need to stay
alive until very shortly before libomptarget is destructed.
Leaving the deinit_plugin calls where initially inserted hits use after
free from the dynamic_module.c offloading test (verified with valgrind
that the new location is sound with respect to this)
