* doc: add a page listing supported proposals

This adds a table showing Wasmtime's support for various WASI proposals,
much like the one available for WebAssembly proposals. This change is
related to [#2423], which provides guidelines for implementing WASI
proposals but was never merged.

  1. The CLI flag name refers to to the --wasi-modules argument of the wasmtime executable; e.g., --wasi-modules=wasi-crypto. See wasmtime run --help for more information on the flag's default value and configuration. ↩︎

  2. Build Wasmtime with --features=wasi-crypto to enable this. ↩︎
