Set TYPE_NONE as type 0 + other type data tweaks

[AsparagusEduardo]

Description

Unlike Natures, Types are having the issue where if it's not defined in a struct, it always defaults to TYPE_NORMAL.
This PR fixes that by changing TYPE_NONE to 0 and shifting all other Types to +1.
It duplicates TYPE_MYSTERY's icon because graphics_file_rules.mk doesn't let you do duplicates.

Also:

• Adjusted MON_DATA_TERA_TYPE's write/read to account for shift in type IDs.
• Moved Gen 1-3 type damage categories to gTypesInfo.
• Moved Tera Type RGB values to gTypesInfo.
• Moved gTypesInfo and sTypeEffectivenessTable to their own file in src/data/types_info.h
• Fixes Hidden Power's type.

Feature(s) this PR does NOT handle:

• I tried to take the chance to update Hidden Power such that you could customize the types allowed for it, but only got as far as adding test functions to set IVs and finishing the Hidden Power's type test.
• Tera Type indicators aren't moved to gTypesInfo (yet).

Off the top of my head, the backward-compatibility concerns are:

1. Has anybody put a type in a var or other saved value? It could come up for projects with getmondata as a script command, although even then I'm not sure if anybody is likely to permanently save the type rather than immediately compare it against something.
2. Has anybody started using teraType, which was added to BoxPokemon in 1.8? This is fixable, we could introduce a table that maps from teraType to type, and from type to teraType, and use that in Get/SetBoxMonData (where we currently have a + 1/- 1).
   EDIT: As Jasper notes in Discord, anybody using upcoming has started using teraType... although only very recently, unless they've been using givemon's teraType parameter in preparation for it being supported.

Set to draft in the meantime while I revert this and use TYPE_NONE instead.

Ready for review. I updated the PR name and description to account for all the new changes.

added missing Tera Indicator stuff in the description

Could you please add this test (I would say the terastal.c file but up to you)?

SINGLE_BATTLE_TEST("(TERA) All types have the correct effectivness")
{
    u32 species;
    u32 type;

    PARAMETRIZE { species = SPECIES_CHIKORITA; type = TYPE_FLYING; }
    PARAMETRIZE { species = SPECIES_CHIKORITA; type = TYPE_POISON; }
    PARAMETRIZE { species = SPECIES_CHIKORITA; type = TYPE_FIRE; }
    PARAMETRIZE { species = SPECIES_CHIKORITA; type = TYPE_BUG; }
    PARAMETRIZE { species = SPECIES_CHIKORITA; type = TYPE_ICE; }
    PARAMETRIZE { species = SPECIES_CYNDAQUIL; type = TYPE_GROUND; }
    PARAMETRIZE { species = SPECIES_CYNDAQUIL; type = TYPE_ROCK; }
    PARAMETRIZE { species = SPECIES_CYNDAQUIL; type = TYPE_WATER; }
    PARAMETRIZE { species = SPECIES_GASTLY; type = TYPE_NORMAL; }
    PARAMETRIZE { species = SPECIES_GASTLY; type = TYPE_GHOST; }
    PARAMETRIZE { species = SPECIES_GASTLY; type = TYPE_PSYCHIC; }
    PARAMETRIZE { species = SPECIES_TOTODILE; type = TYPE_GRASS; }
    PARAMETRIZE { species = SPECIES_TOTODILE; type = TYPE_ELECTRIC; }
    PARAMETRIZE { species = SPECIES_DRATINI; type = TYPE_DRAGON; }
    PARAMETRIZE { species = SPECIES_DRATINI; type = TYPE_FAIRY; }
    PARAMETRIZE { species = SPECIES_SNEASEL; type = TYPE_FIGHTING; }
    PARAMETRIZE { species = SPECIES_SNEASEL; type = TYPE_STEEL; }
    PARAMETRIZE { species = SPECIES_ABRA; type = TYPE_DARK; }

    GIVEN {
        PLAYER(SPECIES_WOBBUFFET) { TeraType(type); }
        OPPONENT(species);
    } WHEN {
        TURN { MOVE(player, MOVE_TERA_BLAST, tera: TRUE); }
    } SCENE {
        if (species == SPECIES_GASTLY && type == TYPE_NORMAL)
            MESSAGE("It doesn't affect Foe Gastly…");
        else
            MESSAGE("It's super effective!");
    }
}

Looks good otherwise

This doesn't account for type changes by the user. I'll add sone assumes.
