#780 Migrate build from webpack to Vite

- Changed build config from webpack to vite (see details below).
- Moved root files to /lib for better code organization, leaving main entry points in root.
- Implemented custom customElement decorator to work around duplicated registrations.

The new configuration produces the following outputs:

- For npm consumers, *.esm.js and *.cjs.js files. The main export exposes helpers, all components can be registered with solid-ui/components, and individual components can be registered with solid-ui/components/*.
- For modern CDNs, we have ESM bundles in *.js files, also allowing all components or invidiual imports. These now include solid-logic and rdflib, no need to load them separatedly.
- For legacy CDNs, we still have the UMD bundles, but those are discouraged and not documented in the README anymore. These ones still externalize solid-logic and rdflib.
