Apply clang-tidy11 to gmxana files with no dependencies

Splitt off from !1433. These are only the gmxana files that do not
depend on other clang-tidy11 changes. The files gmx_analyze.cpp,
gmx_nmr.cpp, gmx_bar.cpp, gmx_wheel.cpp and gmx_energy.cpp all have
dependencies, mostly on enum modernization. They can be a subsequent
MR.
