Packaging: Normalize all qlpack.yml files for all languages

This commit ensures consistency among all of our qlpacks. Here are the
changes:

1. Ensure only modern references are used (codeql-{lang} is converted to
   codeql/{lang}-all or codeql/{lang}-queries where appropriate).
2. Use consistent version numbers. All languages are at 0.0.2 except
   javascript, which is 0.0.3.
3. Convert all `libraryPathDependencies` to `dependencies` with version
   constraints
4. Dependencies from query packs to other packs are always `"*"` since
   these dependencies are always from source and we should get the
   latest.
5. Dependencies from codeql/{lang}-lib to codeql/{lang}-upgrades must
   be strict since there is a tight connection between the libary
   and its relevant upgrades.
