Refactor `JSStringImpl` to use the js-string-builtins API[1]. When the module `WebAssembly.String` is not available we define a "polyfill" with the previous imports, so this change is backwards compatible. Also updates some of the methods to use avoid multiple `this.length` calls (which do an FFI call), and use unchecked getters when possible. A new library `dart:_error_utils` is introduced for faster range and index checks when the length (or max value) is known to be positive (e.g. when it's the length of a string). For now only `JSStringImpl` and `operator []` and `operator []=` of `JSArrayImpl` are updated to use the new range and index checks. Rest of the libraries will be updated separately.
