Added enum for IsMonDisobedient

[Mitsunee]

Adds enum to replace magic numbers returned by IsMonDisobedient

Description

IsMonDisobedient returns magic numbers (0 to 2) and this PR adds an enum:

#define DISOBEDIENCE_OBEDIENT 0
#define DISOBEDIENCE_IGNORED  1 // command is ignored
#define DISOBEDIENCE_OTHER    2 // random move or self-hit

I also noticed that HITMARKER_OBEYS does not necessarily mean that the Pokemon actually obeyed the command, so I'd like to rename that, but didn't have a good idea and just left a comment. It seems the flag is always set, unless the Pokemon chose to use a different move (incl. hitting itself with pseudo-POUND).

This change passes with an actual enum too instead of the #define.

this repository generally uses #define over enum for most cases. I'm aware there is no difference in this case since there's also no typedef used.
