Introduced a cmake variable LIBOMPTARGET_OMPT_SUPPORT that can be used
to control OMPT target support. It follows host OMPT support, controlled
by LIBOMP_HAVE_OMPT_SUPPORT. Added a global constructor in libomptarget
that uses the connector to force registration of tool-provided callbacks
in libomp. A pair of init and fini functions are provided to libomp as
part of the connect process which will be used to register the
tool-provided callbacks in libomptarget.

Depends on D123429 <https://reviews.llvm.org/D123429>
