[ContentPatcher] Support includes for dynamic tokens

[Mushymato]

Summary

Add a way to include dynamic tokens from another file like so:

{
  "$schema": "https://smapi.io/schemas/content-patcher.json",
  "Format": "2.9.0",
  "DynamicTokens": [
    {
      "IncludeFromFile": "dt_include/standard.json"
    },
  ]
}

The file dt_include/standard.json is only allowed to have DynamicTokens section, and dynamic tokens defined inside will behaves as if they were defined at the position of the include in content.json. You can have nested includes, but not repeated include of same file (at the moment).

When is supported for dynamic token includes, and tokens within a include is only evaluated if the include's conditions are all true.

{
  "DynamicTokens": [
    {
      "IncludeFromFile": "dt_include/conditional.json",
      "When": { "Season": "Spring" }
    },
  ]
}

If the When section on an include contains a HasMod condition that will never be true (i.e. mod not installed), the tokens inside will not be added.

In this example, if the dynamic token "MyTok" is defined within dt_include/cmct.json and nowhere else, it will be valid only if Spiderbuttons.CMCT is installed and invalid otherwise.

{
  "DynamicTokens": [
    {
      "IncludeFromFile": "dt_include/cmct.json",
      "When": { "HasMod": "Spiderbuttons.CMCT" }
    },
  ]
}

On the other hand if MyTok is defined like this in content.json, it will only be unready if Spiderbuttons.CMCT is not installed, rather than invalid.

{
  "DynamicTokens": [
    {
      "Name": "MyTok",
      "Value": "Token Value Goes Here",
      "When": { "HasMod": "Spiderbuttons.CMCT" }
    },
  ]
}
