Update: implement append functions for array types and implement all the other functions.

Start implementing all of the macros as real functions for these.
Macros do what I wanted and save writing code, but the binary size is more of a concern.
Switching to explicit functions should also make debugging easier.

The macros may be removed eventually and all of the code utilizing the macros will be updated to use these.

There will be more changes like this going forward in some other projects like f_string and f_utf_string.
