Fix for case when vector iterator is raw pointer

We are using patched libc++ which uses raw pointers for vector itrators
to improve code compilation speed. This commit fixed two compilation
issues in toml11:
 * location::const_iterator deinition assumes that vector const_iterator
   is struct or class type rather than raw pointer.
 * `const const_itetr foo()` triggers `-Wignored-qualifiers` for primitive
   types and `void` which breaks `-Wextra -Werror` compilation.
