Temporary wasm runtime with wasi and wasi-webgpu support

This runtime will be deprecated once more popular runtimes add wasi-webgpu support.

Usage:

It is recommended that you run with the --release flag, as crainlift is slow in debug mode.

cargo run --release [path to wasm component]

Building components that run in graphtime

Please note that graphtime requires guest components to export the wasi:cli/run interface.
