Merge #13558: Drop unused GetType() from CSizeComputer

Browse source 
893628be01 Drop minor GetSerializeSize template (Ben Woosley)
da74db0940 Drop unused GetType() from CSizeComputer (Ben Woosley)

Pull request description:

  Based on conversation in #13462, it seems the serialization `GetType` has very narrow use/effect. In every case except for `CAddress`, which specifically relates to a network peer's address, not a wallet address etc., the serialized representation of an object is irrespective of its destination / type.

  This removes the unused `GetType` method from `CSizeComputer` as a step to further narrowing that use.

Tree-SHA512: e72b8e9e5160396691e05aeaee3aba5a57935a75bd5005cfcc7fb51c936f3d1728a397f999da5c36696506dd815fafa5c738f3894df8864f25f91f639eba9c3d
