An incremental parsing system for programming tools

This resolves https://github.com/tree-sitter/tree-sitter/issues/3454. This brings the usage of wasmtime::Engine in line with how wasmtime intends it to be used. All wasmtime functions that receive an Engine always receive an `&Engine`, never an owned `Engine`. They are always responsible for cloning the reference if they need it. This brings the usage of wasmtime::Engine in line with how TSParser treats TSLanguages: when setting a language to the parser, the parser is responsible for cloning the reference to the TSLanguage. It is counterintuitive for TSParser to have different behavior when receiving wasmtime_engine_t. C API users also expect this behavior, see "Memory Management" [here](https://docs.wasmtime.dev/c-api/wasm_8h.html). Talking about the C API: without this change, failing to clone the `wasmtime_engine_t` (which, again, is never something API users need to do in wasmtime) and then reusing the engine in multiple TSLanguages results in a use after free. With this change, failing to call `wasm_engine_delete` on your owned Engine results in a memory leak. Memory leaks are safer than use-after-free. |

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
