…ative systems -> A working version of this implementation is added for the GLM-MHD system -> The flux-differencing formula requires non-conservative terms of the form (local * symmetric)... I modified equations/ideal_glm_mhd_2d.jl and solvers/dgsem_tree/dg_2d.jl to make it work -> In this first implementation, we only use the Powell term and deactivate the GLM term

This PR extends the subcell limiting strategies implemented in #1476 to non-conservative systems.
To do the subcell limiting, the DGSEM is formulated as a flux-differencing formula. For non-conservative systems, this formulation requires expressing non-conservative terms as the product of both local and symmetric components. We have included an example using the GLM-MHD equations, where the Powell and GLM non-conservative terms have been recast in the format of "local * symmetric."
