This patch implements text and binary encoding/decoding support for the stack switching proposal. It does so by adapting the previous typed-continunations implementation. Particular changes: * Support for new `resume` encoding. * Added support for `resume_throw` and `switch`. * Feature flag `typed-continuations` has been renamed to `stack-switching`. A small unfortunate implementation detail is that the internal name `Switch` was already taken by the `br_table` instruction, so I opted to give the `switch` instruction the internal name `StackSwitch`. A minor detail is that I have reordered the declarations/definitions of the stack switching instructions such that they appear in ascending order according to their opcode value (this is the same order that the stack-switching explainer document present them in). I can look into adding validation support in a subsequent patch.
