Server: Generate enums from tweakdbstr at build time

[MeFisto94]

And commit the results so tweakdbstr.txt is not required to build the code. It may be done whenever there's adjustments to the tweakdbstr or like only once.

What counts is that we have something like:

namespace Cyberverse.Server.TweakDb.Generated;

public enum Character {
  Judy,
  Panam
}

Maybe we'd also want actual class members instead of an enum, so we can directly grab the string "Character.Panam" or their uint crc32 hash from them.
