Build: Modernize the build infrastructure

Replace Grunt with custom Node.js build scripts. Switch from JSHint
to ESLint with a flat config. Replace TestSwarm with jQuery Test Runner
(jtr) and update QUnit to 2.x. Add GitHub Actions CI and release-it
for publishing to npm.

Update tests to QUnit 2.x API: use `QUnit.test`/`QUnit.module`, `assert.*`,
`assert.async()`. Use `.on()`/`.off()` instead of `.bind()`/`.unbind()`,
and `jQuery` instead of `$`.

Add `.editorconfig`, `.mailmap`, and npm "files" field to enable proper
installation from npm.

Bump version to `2.0.0-pre`.
