Lowers these extension methods to some helper functions instead of allowInterop to improve performance and get consistent semantics. Specifically: - Function.toJS no longer gives you the same JSFunction when calling toJS on the same function multiple times in the JS compilers. - Adds fast calling syntax for functions with 0-5 args in the JS compilers. - Allows additional args to be passed to converted functions that are omitted in the JS compilers. - The static type now determines the number of args that can be passed to the JS function in the JS compilers. - Fixes an issue in dart2wasm where if too few arguments are passed, the call may succeed due to conversion of undefined to null. - Adds throws when a user tries to wrap a JS function that returned from Function.toJS in the JS compilers.
