Bug 37824: Replace webpack with rspack for fun and profit

I left the webpack.config.js as well as the devDependencies in place for now.
We can remove them in a follow-up patch on this bug after testing it out.

To test:
1) Run js:build and js:build:prod
2) Note the build time
3) Apply patch
4) Run yarn install
5) Run js:build and js:build:prod again
6) Note the much faster build time
7) Extra credit: take a look at the ERM or preservations module and make sure everything works as expected.
8) Extra credit: run the cypress tests.
9) Sign off or give your opinion

Looks faster to me. Where webpack failed for me (Killed, error 137), this passed.
