[Flang][OpenMP] Enable no-loop kernels (#155818)

Enable the generation of no-loop kernels for Fortran OpenMP code. target
teams distribute parallel do pragmas can be promoted to no-loop kernels
if the user adds the -fopenmp-assume-teams-oversubscription and
-fopenmp-assume-threads-oversubscription flags.

If the OpenMP kernel contains reduction or num_teams clauses, it is not
promoted to no-loop mode.

The global OpenMP device RTL oversubscription flags no longer force
no-loop code generation for Fortran.
