Add function barrier to fix HG shock capturing on macOS ARM

[efaulhaber]

Closes #1457.

Other example files using IndicatorHennemannGassner were also broken on macOS ARM. These were fixed as well.
E.g., p4est_2d_dgsem/elixir_euler_blast_wave_amr.jl and tree_3d_dgsem/elixir_euler_shockcapturing_amr.jl.

Thanks a lot for the quick fix!

Note that when this is approved, the same should be done for the other indicators as well.

Good point. Once your approach chosen here gets the green light of @sloede, the other indicators should be adapted in the same way - but maybe in another PR
