split c-linter action in 2

[zingale]

Right now the c-linter action does clang-tidy and claims to do cppcheck. We should split it in two.

For the clang-tidy, we should use the build process that is in AMReX currently (USE_CLANG_TIDY=TRUE).

For cppcheck, we should make sure it is actually running and make an artifact from the output.

One of the considerations is that cppcheck uses a compilation database to pick up the right options and files. It might be possible to do something with make print-CXXFLAGS etc instead, but I'm not sure.

we now have a separate clang-tidy action, so I am not sure if we even need this one anymore.
