An incremental parsing system for programming tools

The `Emoji` property alias is already present, but the actual property is not available since it lives in a new file. This adds that file to the `generate-unicode-categories-json`. The `emoji-data` file follows the same format as the ones we already consume in `generate-unicode-categories-json`, so adding emoji support is fairly easy. his, grammars would need to hard-code a set of unicode ranges in their own regex. The Javascript library `emoji-regex` cannot be used because of #451. For unclear reasons, the characters #, *, and 0-9 are marked as `Emoji=Yes` by `emoji-data.txt`. Because of this, a grammar that wishes to use emojis is likely to want to exclude those characters. For that reason, this change also adds support for binary operations in regexes, e.g. `[\p{Emoji}&&[^#*0-9]]`. Lastly (and perhaps controversially), this change introduces new variables available at grammar compile time, for the major, minor, and patch versions of the tree-sitter CLI used to compile the grammar. This will allow grammars to conditionally adopt these new regex features while remaining backward compatible with older versions of the CLI. Without this part of the change, grammar authors who do not precompile and check-in their `grammar.json` would need to wait for downstream systems to adopt a newer tree-sitter CLI version before they could begin to use these features. |

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
