Add needs_facet_permutations flag

[mscroggs]

Currently, for all facet integrals, DOLFINx creates the entity permutation info and passes it into the kernel: see eg https://github.com/FEniCS/dolfinx/blob/3d11b33af6a41ebc596650b78ef347932b2b79c0/cpp/dolfinx/fem/assemble_matrix_impl.h#L474. Inside create_entity_permutations, all the entities are created (https://github.com/FEniCS/dolfinx/blob/1b0e5ed457fc57735c896e1732e231e3b8cdb47c/cpp/dolfinx/mesh/Topology.cpp#L246-L247). These entities can take up quite a bit of memory and aren't always needed.

The code generated by FFCx for a form should have a bool (called something like needs_facet_permutations) that indicates whether or not this informations is actually needed in the kernel. I think it is only needed when a term like a["-"] * b["+"] is in the form.
