cargo binstall support

[rajsite]

Many of the other bytecodealliance tools support cargo-binstall based installation, for example:

• wasmtime: https://docs.wasmtime.dev/cli-install.html#install-via-cargo
• wkg: https://github.com/bytecodealliance/wasm-pkg-tools?tab=readme-ov-file#installation
• wasm-tools: https://github.com/bytecodealliance/wasm-tools?tab=readme-ov-file#installation
• wac: https://github.com/bytecodealliance/wac?tab=readme-ov-file#installation
• wit-bindgen (which works with cargo binstall wit-bindgen-cli but is not documented): https://github.com/bytecodealliance/wit-bindgen?tab=readme-ov-file#cli-installation

Would be great for that support in wasi-virt too!
