Use C string instead of chunk for code info and literal

Use zero-terminated C strings instead of cmark_chunks without storing
the length. The length of code literals will be readded in a later
commit. strlen overhead for code info should be negligible.

Reduces size of struct cmark_node by 8 bytes.
