This PR improves the vscode syntax highlighting.

- Added `comment` keys.

- Added `const` to modifier keywords.
- Removed `addr` keyword.
- Refactored some rules to use `begin`/`end` to handle line breaks.
- Added highlighting to `choice` values as `enum` values.
- Updated the rules for matching `types`.
- Added highlighting to rhs of `adapt`, `alias`, `choice`, `constraint`,
`impl`, `interface`, `as`, and `impls`.
    - Added highlighting to rhs of bindings.
    - Added highlighting to function return types.
- Updated the rules for matching `functions`.
- Updated the rules for matching `variables`.
