[UR] Revamp README file a little

- add TOC to the top-level README file,
- order sections and group them together (incl. new Contrib section),
- clean and unify Markdown syntax a little,
- add new badges for CodeQL and Bandit,
- fix main GHA badge to point to a specific ('cmake') workflow.

+### Weekly tags
 
 Each Friday at 23:00 UTC time a [prerelease
 tag](https://github.com/oneapi-src/unified-runtime/releases) is created which
 takes the form `weekly-YYYY-MM-DD`. These tags should be used by downstream
 projects which intend to track development closely but maintain a fixed point in
 history to avoid pulling potentially breaking changes from the `main` branch.
