tgui maintenance chores (#60859)

## About The Pull Request

**Upgrades:**

- Yarn 3.0
- TypeScript 4.3
- Sass 1.37
  - Required some refactoring of `/` into `math.div()` in CSS

**Dependency removals:**

- Removed ESM package, see: https://github.com/standard-things/esm/pull/902

I initially thought it was impossible to stop relying on this package, but fortunately, ES module support in Node 12+ now comes standard and I only had to convert the very few external module imports to `require()` (because Yarn PnP).

I also moved `logging.js` directly into `tgui-dev-server` package, because that's where it is used. One less internal dependency.

**Sidegrades:**

- Removed creation of a common tgui chunk, because in practice it creates unnecessary complexity (devs sometimes get a white screen due to this chunk being invalid) and doesn't really save that much data on CDN, and **definitely** doesn't make tgui load faster.

I think that is all. I tested it a bit and everything seemingly works.
