Using a parameter in a palette which is defined in a different palette doesn't work

[Milopetilo]

Describe the bug

When making use of a parameter in a palette which uses a different palette that has the parameter, eg. carpet_color_type from parametrized_carpets_palette, the game throws an error.
This only occurs when the palette that is using the other palette defines its own symbols for the parameter, for example

    "type": "palette",
    "id": "collapsed_tower",
    "palettes": [ "parametrized_concrete_carpets_palette" ],
    "terrain": {
      ...
      "r": { "param": "carpet_color_type", "fallback": "t_carpet_red" },
      ...

throws mapgen 'palette collapsed_tower' uses undefined parameter 'carpet_color_type'.

Attach save file

N/A

Steps to reproduce

Replace data/json/mapgen_palettes/collapsed_tower.json with this one collapsed_tower.json.
Alternatively add any palette that has parameters (such as parametrized_carpets_palette) to another palette and make a symbol use the parameter by adding { "param": "carpet_color_type", "fallback": "t_carpet_red" } to any symbol.

Expected behavior

To have the game not throw an error and use the parameter from the other palette, just like it does when using it in a map.
