feat(tm2): add sdk/params module

[moul]

• port x/params -> sdk/params b930513
• inject in vmkeeper + add std.SetConfig 602245d
• implement in gnoland 783a044
  • appchain
  • rpc query
  • txtar
• implement or add comment where we should use it in the existing codebase
  • namespace's realm target
• questions
  • do we want a std.GetConfig from the contract part? -> No, it allows unsafe, complex, and implicit patterns. If you want to get a value from another contract, you can either import it or use a registry pattern. This approach preserves type safety and other GNOVM protections.
  • do we want to restrict the realms able to call SetConfig (only r/sys), or maybe set an expensive gas price?
• after discussion with jae
  • Rename Config -> Param for consistency
  • Remove interface{} from the setters and use specific types, including in the tm2 implementation (string, uint64, int64, bool, bytes)
  • Remove the .<type> suffix addition, but ensure that the type is explicitly defined by the user; and remove the table.
  • Remove the types table from the tm2 implementation

do we want a std.GetConfig from the contract part? -> nope

Could you elaborate on why this decision ?
