Move extern cmap declarations from .cpp files into new .h files.

That way, the compiler can check them against the definitions rather
than just relying on the linker to line things up.

Make the types of the declarations and definitions match exactly,
instead of being synonym typedefs of each other.

Fix some IWYU and use FX_ArraySize where possible.
