[bos #38045][bos #38046] New SA versions of NETGEN and GMSH.

Add netgen_runner_test for 1D2D3D

add test for gmsh_runner

Improve test for netgen and gmsh. Add new versions in option mesher_launcher.py

Add test for Netgen2D SA version.

Test for Netgen 2D SA version.

Code cleanup.

Adapt mesher_launcher and add creating_parallel_gmsh_mesh.py test for Remote version of 3D GMSH.

test for parallel mesh for 2D using new netgen SA/Remote version. Add the possibility to export Mesh1D.med in SMESH_Gen.cxx at method parallelComputeSubMeshes. Modify the constructor of ParallelMesh class in smeshBuilder to handle 2D meshing in parallel.
