Lint unsupported web API usage with the Browserslist support matrix.
Detection seems simplistic. For example, defining and using a function
called "fetch" triggers a false positive that must either be disabled at
each reference, claiming that fetch has a global polyfill (shown below
via settings), or renaming the symbol (done in this patch). It also
fails to detect missing APIs like Object.entries(). Because of these
shortcomings, I don't think we're going to get as much value out of it
as we'd hoped. However, I'm happy to give it a try if others disagree.

For some reason, overrides work to suppress some issues flagged in tests
but not others which seems like a bug. This patch point suppresses a
Promise usage as a workaround.

Example of claiming is polyfilled in the ESLint settings:

	"settings": {
		"polyfills": [ "fetch" ]
	}
