Test intel compilers

[IgorBaratta]

Tests with classic Intel compilers are disabled due to an issue with pybind.
Once that is solved I can re-enable the tests.

Fix expected to pybind version 2.6.2:
pybind/pybind11#2771

Have we lost the C++ build test with the classic Intel compiler?

Last time I tried, there were some template type inferences that we use quite a lot that Intel doesn't seem to support.

Actually, the issue is building basix, it also uses pybind..
We can install it using gcc, to allow the C++ build test with the classic compiler.

Ah, ok. Let's create an issue so we don't forget it.

@jhale There's been quite a bit of work on pybind11 for the Intel classic compilers: pybind/pybind11#2573.

Also see pybind/pybind11#2769 and pybind/pybind11#2771.

Last time I checked there was an issue simply building C++ DOLFINX with Intel Classic, e.g. lines like this:

https://github.com/FEniCS/dolfinx/blob/master/cpp/dolfinx/fem/assemble_vector_impl.h#L542

Intel classic couldn't infer the template type of the function from the argument.

Intel class does work now for DOLFIN C++. Testing has been disabled because basix uses pybind11, which causes a problem.
