build: Enable OpenMP by default, remove experimental warning (bug #42176)

compiler flags instead of OCTAVE_CHECK_OPENMP and case statements.
Delete warning message about OpenMP being experimental.
* ax_openmp.m4: New macro.
* acinclude.m4 (OCTAVE_CHECK_OPENMP): Delete macro definition.
* m4/module.mk (EXTRA_DIST): Include m4/ax_openmp.m4 in the list.
* NEWS: Mention that OpenMP is enabled by default.
