Set up jsbundling-rails to transpile and bundle javascript

[joncameron]

Description

Setting up jsbundling-rails to transpile and bundle our javascript assets. Moving to jsbundling-rails does remove support for hot module replacement and code splitting, but we may not need those features or have them enabled previously.

Done Looks Like

• Add and configure jsbundling-rails
• Convert Coffeescript to vanilla JS
• Investigate transitioning to esbuild-loader for JSX files
