[SofaFramework] Add tests on aliases for "multiple projects" out-of-tree build

[fredroy]

While making out-of-tree builds with SofaGLFW, which entrypoint is a a cmakelists with two add_sofa_something(), cmake is throwing this kind of error while reading the second project:

CMake Error at C:/Work/sofa/install/master_fredroy/lib/cmake/Sofa.DefaultType/Sofa.DefaultTypeConfig.cmake:44 (set_target_properties):
  Attempt to promote imported target "Sofa.DefaultType" to global scope (by
  setting IMPORTED_GLOBAL) which is not built in this directory.

which appears (after some headaches) to be linked with the fact that the Sofa.DefaultTypeConfig is read twice and cmake tries to set a flag (imported global) on something which has already the flag, and more generally to do twice the job of aliasing.

So this PR adds a test on the four "legacy" SofaFramework targets to only make aliases if it was not done before.

And for good measure, update the date for the removal of the aliases to v22.06
