[Clang][OpenMP] Switch to __kmpc_parallel_60 with strict parameter (upstream #171082)

[ro-i]

Adopt Kevin's upstream PR llvm#171082 for amd-staging.

Note: The following tests did not fail due to kmpc_parallel_51/60 renaming and seem to have no offloading anymore:

clang/test/OpenMP/amdgcn_target_device_vla.cpp
clang/test/OpenMP/amdgpu_target_with_aligned_attribute.c
clang/test/OpenMP/target_teams_generic_loop_codegen_as_parallel_for.cpp

See commit "make failed tests work, but not good".

(Do not merge without waiting for PSDB results.)

wait, my bad, the stuff that's being removed there had been added by cherry-picking Kevin's commit from upstream. So it just sets the state of the tests back. Should thus be fine

(but some MLIR tests still need adaption)
