Update webpack and related libs to newest versions

[jpolitz]

This commit updates webpack to the newest version and enables building on node 20+. There are a lot of details here.

• Had to patch in versions: {node:...} to browserify's process object (is-core-module, which we rely on, needs this and I couldn't figure out how to configure browserify for it)
• Had to change how polyfills were included in builds for crypto, stream, path, and so on
• Some updates also updated typescript, and I didn't want to mess with tsconfig since things were building OK, so I added explicit anys and did some casting/checking to get around small TS updates; there should be no semantic change to that code.
• I regenerated webpack.config.js from scratch from the webpack-cli tool rather than trying to edit the existing one; I think this was the right decision and let me identify which plugins/provides we were using from the ground up.

I think there are things we can remove from both package.jsons, but that's maybe an analysis for another day.

I also need to debug a message that prints (but seems to not stop or otherwise affect the build creating the needed files?). So this isn't yet ready to merge, more work to do, but basically at the point where I got a local build to start up the editor and create files, run image library stuff, etc.

OK found the culprit which was indeed a bad regex we wrote in dead code in the codemirror mode:
