Remove incorrect condition that would prevent balancing of repeating
structures containing only tokens (nodes w/ no children).

Courtesy of @Eli-Zaretskii, these fixes should unblock people from
building tree-sitter with MinGW.
I don't think this is an unreasonable maintenance burden, especially
given the Emacs project's interest in using tree-sitter, but
@maxbrunsfeld gets the final call.
Building `query.c` requires `TREE_SITTER_LANGUAGE_VERSION_WITH_SYMBOL_DEDUPING` which is defined in `language.h`.
It produces an error:
```
query.c:744:40: error: use of undeclared identifier 'TREE_SITTER_LANGUAGE_VERSION_WITH_SYMBOL_DEDUPING'
```
when building with cgo.
* Remove dependency on utf8proc
This removes the only external dependency on utf8proc for UTF-8 decoding. It does so by implementing its own UTF-8 decoder. This decoder is both faster and has a simpler API.
* .gitmodules: remove utf8proc submodule
* docs/section-2-using-parsers.md: remove requirement for utf8proc submodule
* docs/section-6-contributing.md: likewise
* lib/Cargo.toml: remove utf8proc subdirectory package include
* lib/README.md: remove utf8proc subdirectory description
* lib/binding_rust/build.rs: remove utf8proc compiler include directory
* lib/src/lexer.c: remove utf8proc dependencies and types
* lib/src/lib.c: remove utf8proc dependency
* lib/src/unicode.h: define types for Unicode decoders
* lib/src/utf16.{c,h}: implement more readable UTF-16 decoder
* lib/src/utf8.{c,h}: implement fast UTF-8 decoder
* lib/utf8proc: remove utf8proc submodule directory
* script/build-lib: remove utf8proc compiler include directory
* script/build-wasm: likewise
* Optimize ts_lexer__get_lookahead.
Try to favor non-failure code path and assign lookahead values directly to lexer
* lib/src/lexer.c: optimize for non-failure code path
* Fix some compiler errors
* lib/src/lexer.c: cast from signed to unsigned for decode_next result
* lib/src/utf16.c: fix non-constant initializers for older compilers
* Remove some missed remnants of utf8proc
* docs/section-2-using-parsers.md: only two include paths necessary now
* lib/src/lib.c: no need to define UTF8PROC_STATIC
* Use ICU's utf8 and utf16 decoding routines
* Remove unnecessary casts when calling icu macros
* Check buffer length before attempting to decode a unicode character
* Use new unicode function when parsing Queries
