Provide non-minified distribution

See original GitHub issue

The current way VegaLite distributed is by including minified version only

<script src="https://cdn.jsdelivr.net/npm/vega@5.9.0"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-lite@4.0.2"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-embed@6.2.1"></script>

If error thrown (like example below), it’s very hard to figure out what’s went wrong

ERROR TypeError: Cannot read property 'length' of undefined
    at vega-5.9.0.js:1
    at Array.reduce (<anonymous>)
    at vega-5.9.0.js:1
    at Array.forEach (<anonymous>)
    at Mt (vega-5.9.0.js:1)

    at nu.ot.transform (vega-5.9.0.js:1)
    at nu.Kr.evaluate (vega-5.9.0.js:1)

For example, you can load non-minified Vega-Lite with:

<script src="https://cdn.jsdelivr.net/npm/vega-lite@4.0.2/build/vega-lite.js"></script>

I’ll add a debugging guide in a follow-up pull request.
