Crate wasi_preview1_component_adapter_provider

This crate contains the binaries of three WebAssembly modules:

• WASI_SNAPSHOT_PREVIEW1_REACTOR_ADAPTER
• WASI_SNAPSHOT_PREVIEW1_COMMAND_ADAPTER
• WASI_SNAPSHOT_PREVIEW1_PROXY_ADAPTER

These three modules bridge the wasip1 ABI to the wasip2 ABI of the component model.

They can be given to the wit_component::ComponentEncoder::adapter method, using the WASI_SNAPSHOT_PREVIEW1_ADAPTER_NAME, to translate a module from the historical WASM ABI to the canonical ABI.
