Build and minify the Web UI using swc instead of babel, tsc and terser.
This results in a significant speedup of the build process as it skips
checking types and uses native code to do the minification.
To prevent accidental type errors being introduced the TypeScript
compiler is still used to perform type checking on the Web UI files.
Due to peer dependency resolving shenanigans the swc/core package had to
be added to the workspace, controller and web_ui to avoid pnpm creating
a duplicate install of webpack that break the build.
Rename the config files for the browser build of modules to better
communicate that it's purpose is to compile code for a browser
environment rather than the Web UI in particular. This also aligns with
the "browser" option in package.json, the existing browser.ts entrypoint
in lib, and how the browser environment is typically referred to.
