Fix #472: Emscripten Frontend (#662)
* Fix #472: Add Emscripten/WebAssembly build for browser-based ChaiScript

Port Rob Loach's ChaiScript.js work (https://github.com/RobLoach/ChaiScript.js)
into the main repository as an Emscripten build target. Adds a GitHub Actions
workflow that builds ChaiScript to WebAssembly and publishes artifacts (JS, WASM,
HTML) for embedding in the official ChaiScript.com website. Includes an HTML
interactive playground frontend and a native test validating the eval API surface.

* Address review: publish WASM assets as release under wasm-latest tag

Add a publish job to the emscripten workflow that creates a prerelease
tagged wasm-latest with chaiscript.js, chaiscript.wasm, and
chaiscript.html as downloadable assets. Runs only on pushes to the
develop branch. The website repo can fetch these via the public
GitHub Releases API on a daily cron without any cross-repo auth.

Requested by @lefticus in PR #662 review.
