J_1 J_2 model GCI

[marekgluza]

The J1 J2 mode is defined

• it is still 2 local in the sense of compiling even though the range is 2 local

• 

• [ ] decide if to use the compiling approach here https://github.com/qiboteam/boostvqe/blob/c6da8c5d4ee02a3b3f765323dadde7d73034ef3f/src/boostvqe/compiling_XXZ.py#L53-L60 vs just create symbolic hamiltonian and run #69

• [ ] I suggest that we parallelize: @shangtai populates the gates and @jykhoo1987 does #69 first

• 70 is less priority as we don't run much with it
