Problem: Installing treesitter parser is hard (harder than climbing to heaven). Solution: Add optional support for wasm parsers with `wasmtime`. Notes: * Needs to be enabled by setting `ENABLE_WASMTIME` for tree-sitter and Neovim. Build with `make CMAKE_EXTRA_FLAGS=-DENABLE_WASMTIME=ON DEPS_CMAKE_FLAGS=-DENABLE_WASMTIME=ON` * Adds optional Rust (obviously) and C11 dependencies. * Wasmtime comes with a lot of features that can negatively affect Neovim performance due to library and symbol table size. Make sure to build with minimal features and full LTO. * To reduce re-compilation times, install `sccache` and build with `RUSTC_WRAPPER=<path/to/sccache> make ...`
