Subject: [PATCH] #1398 Change teat utility used from Catch2 to Boost.Test.

The reason for the change was partly bug #1363: tests were failing for macOS / shared library / release mode solely due to an internal error of Catch2.

Now we need to have Boost Test installed (as usual ThirdPartyCompilationLibrary facility provides it).

I also used the modifications to refresh the way tests were written:

- Fixture are now handled in a much better way; in peculiar some tests no longer required a fake model and its equally fake Lua file to proceed.
- The model tests have been refined to provide more information in case of failure (the complete path of the files that might not be equal are now directly given).
- Mpi fixture is now working completely: you may define several test suites in an executable without having it fail (previously it was the case only for the full-fledged model fixture).

This commit is unusually big for me, but that is due to the fact with macro everywhere in both Boost.Test and Catch2 I had rather not used them at the same time.

 This check was introduced to test the new feature of environment variable in MoReFEMData; other aspects of this class that could be
 tested as well aren't yet handled.
 
-However, it must be noticed this is a very tricky class to handle: as Mpi initialization is performed inside, we can't run different test cases, as
-MPI_Init() and MPI_Finalize() can be called only once per program. So when more tests are added it might be useful to introduce others
-main files for these tests.
