Add all RCT1 walls

[ZeeMaji]

Adds all of the RCT1 walls with different heights/colors as compat objects. For the RCT1AA glass wall i've taken the liberty of making the frame remappable for consistency with the RCT2 glass walls.

Currently the sceneryGroup option only allows for one scenery group. So the themed walls will be placed only within their original scenery groups and not within the general fences scenery group.

Note for maintainers: There's some hard coded color converters in S4Importer.cpp within ConvertWall, these will need to be changed to import the brown wooden fence gate properly and to remove the wooden fence color remapping that will be made redundant by these walls.

Could you provide a screenshot of their differences? There are some walls in this PR I didn’t hear about before.

[ZeeMaji]

Sure.

Green tile = RCT1
Red tile = RCT2

these will need to be changed to import the brown wooden fence gate properly

Can you clarify this? Seems the brown wooden fence gate has something specific going on?

Within ConvertWall in S4Importer, there's a switch case that remaps colors of walls during S4 import

void ConvertWall(const int32_t& type, colour_t* colourA, colour_t* colourB)

    {
        switch (type)
        {
            case RCT1_WALL_TYPE_WOODEN_PANEL_FENCE:
                *colourA = COLOUR_DARK_BROWN;
                break;
            case RCT1_WALL_TYPE_WHITE_WOODEN_PANEL_FENCE:
                *colourA = COLOUR_WHITE;
                break;
            case RCT1_WALL_TYPE_RED_WOODEN_PANEL_FENCE:
                *colourA = COLOUR_SALMON_PINK;
                break;
            case RCT1_WALL_TYPE_WOODEN_PANEL_FENCE_WITH_SNOW:
                *colourA = COLOUR_DARK_BROWN;
                break;
            case RCT1_WALL_TYPE_WOODEN_PANEL_FENCE_WITH_GATE:
                *colourB = *colourA;
                *colourA = COLOUR_DARK_BROWN;
                break;
            case RCT1_WALL_TYPE_GLASS_SMOOTH:
            case RCT1_WALL_TYPE_GLASS_PANELS:
                *colourB = COLOUR_WHITE;
                break;
            case RCT1_WALL_TYPE_SMALL_GREY_CASTLE:
            case RCT1_WALL_TYPE_LARGE_GREY_CASTLE:
            case RCT1_WALL_TYPE_LARGE_GREY_CASTLE_CROSS:
            case RCT1_WALL_TYPE_LARGE_GREY_CASTLE_GATE:
            case RCT1_WALL_TYPE_LARGE_GREY_CASTLE_WINDOW:
            case RCT1_WALL_TYPE_MEDIUM_GREY_CASTLE:
                *colourA = COLOUR_GREY;
                break;
        }
    }

The brown wooden fence gate (RCT1_WALL_TYPE_WOODEN_PANEL_FENCE_WITH_GATE) has it's RCT1 primary color set to it's OpenRCT2 secondary color during importing as the RCT2 wooden fence gate uses the secondary color for the gate, while RCT1 uses the primary color for it.
