[dart2wasm] Remove short input threshold to fall back to native UTF-8 decoder When decoding a JS array input as UTF-8 we currently fall back to the decoder implemented in Dart when the input is small. When benchmarked with `benchmark_harness`, for one byte array, I get 6.0us when decoded with the Dart decoder, and 5.8us when decoded with JS `TextDecoder`. So it looks like Dart decoder is never faster when the input is a JS array. Remove the threshold and always call JS when the input is a JS array. (This threshold was copied from dart2js, where accessing JS data is less expensive.)

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
See LICENSE and PATENT_GRANT.
