✨ Add 08-Wasm Light Client

[jim380]

⚠️ This will require:

• 08-wasm client to be supported in ibc-go v8
• A chain upgrade to activate the new 08-wasm client module.

Problems

• Chain devs are responsible for instantiating light clients that track the consensus of non-CometBFT chains
• Adding new light clients have always required chain upgrades

Solutions

• Host light client contract bytecode (compiled from any language) for the module to interact with
• New light clients can be added via governance proposals, with no changes to the chain codebase
• Existing wasm clients can be upgraded via MigrateContract (recommended only for emergencies)

Example Use Case

• For starters we could host the contract bytecode for the ICS-10 GRANDPA client which would enable the connections between Seda <> Polkadot
• Seda <> Near
