Keep track of the digests of committed transfers so that they can be
used later when handling duplicate observations / VAAs. When processing
an observation or VAA with the same (chain, address, sequence) tuple as
a committed transfer, return a "message already processed" error when
the digests match and a "digest mismatch" error when they don't. The
latter implies a very serious issue because transfer details shouldn't
change once they have been observed by a quorum of guardians.
Add support for handling chain registration VAAs for the tokenbridge
contract. This will let us deploy accounting without also having to
deploy the tokenbridge.
* sdk/rust: Move profile settings to workspace
* sdk/rust: Add serde_wormhole crate
The serde_wormhole crate implements the wormhole wire format as a serde
data format. This will let us replace all the hand-rolled
serialization with auto-generated code, which is less error-prone and
easier to review.
* sdk/rust: Add serde-based struct defintions
Refactor the core crate to add serde-based struct definitions for the
various messages used by the different wormhole smart contracts. This
will also make it easier to use alternate data formats (like json) for
client-side tooling.

* sdk/rust: Drop references to `de::Unexpected`
The `de::Unexpected` enum from serde has a `Float(f64)` variant.
Referencing this enum anywhere in the code will cause the compiler to
emit its `fmt::Display` impl, which includes an `f64.load` instruction
on wasm targets. Even if this instruction is never executed, its mere
existence will cause cosmos chains to reject any cosmwasm contract that
has it.
Fix this by removing all references to `de::Unexpected`.
* cosmwasm: Use cargo resolver version "2"
Enable the new feature resolver for the entire workspace. This
prevents features that are enabled only for dev builds from also being
enabled in normal builds.
* Move cosmwasm Dockerfile to root directory
The cosmwasm contracts now also depend on the rust sdk so the docker
build context needs to be set to the root directory rather than the
cosmwasm/ directory.
* cosmwasm: Add wormchain-accounting contract
This contract implements tokenbridge accounting specifically for the
wormchain environment.
Fixes#1880.
