  Log Message:
  -----------
  [LIBOMPTARGET]Fix PR44933: fix crash because of the too early deinitialization of libomptarget.

Summary:
Instead of using global variables with unpredicted time of
deinitialization, use dynamically allocated variables with functions
explicitly marked as global constructor/destructor and priority. This
allows to prevent the crash because of the incorrect order of dynamic
libraries deinitialization.
