This PR is a continuation of #8615. I merged the previous one by mistake before it was ready.

When an atom is created, we now create a binary literal of it, so that atom_to_binary returns the pre-allocated binary literal instead of a newly converted one.

In atom.h, the name field in the atom struct is changed to a union of an original name (byte*) and an Eterm binary. The former is used by templates when creating an atom. The latter is used when the atom is in the table, therefore also for atom_to_binary.

erl_global_literals.h and erl_global_literals.c are also redesigned. Previously, lambdas in export.c and atoms in atom.c both allocate literal areas separately, without using the global literals interface. Now they both use the new interface of erl_global_literals, so that literal areas are allocated and registered in the same way for lambdas, atoms, and all other global literals. Helper functions like atom_text_alloc() and more_atom_areas() are removed from atom.c, as they are now handled by functions in erl_global_literals.c.

`erl_global_literals` has been redesigned to be more dynamic, allowing any global literal to be created, rather than a small set of literals. Lambdas for exports will now use this interface. The next commit will change atoms to also do that.
