This PR improves the vscode syntax highlighting.
- Added `comment` keys.
- Added highlighting of invalid numbers such as `0x`, `0b`, `0xa`, etc.
- Restricted highlighting of numeric type literals to common types to
avoid highlighting identifiers such as `i1`.
- Changed the highlighting of named operators (e.g., `as`).
- Added `char` and `str` to type literals.
- 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`.
- Added highlighting unidentified words as `variable`.
- Added examples and before/after screenshots.
