misc/wasm: add mention of polyfill for Edge support

Edge supports WebAssembly but not TextEncoder or TextDecoder.
This change adds a comment pointing to a polyfill that could
be used. The polyfill is not added by default, because we want to
let the user decide if/how to include the polyfill.

Fixes #27295
