Binaryen.js now uses binaryen (was Binaryen) as its global
name to align with the npm package. Also fixes issues with
emitting and testing both the JS and Wasm builds.

This PR enables compiling Binaryen to WebAssembly when building binaryen.js. Since WebAssembly is best compiled and instantiated asynchronously in browsers, it also adds a new mechanism to tell if respectively when the module is ready by means of one of the following:
// Using a promise
const binaryen = require("binaryen");
binaryen.ready.then(() => {
... use normally ...
});
// Using await
const binaryen = require("binaryen");
(async () => {
await binaryen.ready;
... use normally ...
})();
// Where top-level await is available
const binaryen = await require("binaryen").ready;
... use normally ...
One can also tell if Binaryen is already ready (for example when assuming it in follow-up code) by:
if (/* we already know that */ binaryen.isReady) {
... use normally ...
} else {
throw Error("Binaryen is supposed to be ready here but isn't");
}
The JS test cases have been updated accordingly by wrapping everything in a test function and invoking it once ready. Documentation will have to be updated as well to cover this of course. New file size is about 2.5mb, even though the Wasm becomes inlined into the JS file which makes distribution across different environments a lot easier.
Also makes building binaryen (to either js or wasm) emit binaryen.js, and not binaryen_js.js etc.
Supersedes and thus fixes #1381
With .ready it also fixes #2452

Without `assert`, even if a test does not validate, the errors will only
show up in its corresponding `.txt` file while the test will succeed.
This makes sure it errors out when a test fails to validate. This also
adds validation checks if there is none.

* Add optimize, shrink level and debug info options to C/JS
* Add instantiate functionality for creating additional unique instances of the API
* Use a workaround when running tests in node
Tests misuse a module as a script by concatenating, so instead of catching this case in the library, catch it there
* Update sieve test
Seems optimized output changed due to running with optimize levels 2/1 now
* Use the options with all pass runners
* Update relooper-fuzz C-API test
* Share defaults between tools and the C-API
* Add a test for optimize levels
* Unify node test support in check.by and auto_update_tests.py
* Also add getters for optimize levels and test them
* Also test debugInfo
* Add debug info to C tests that used it as well
* Fix missing NODEJS import in auto_update_tests
* Detect node.js version (WASM support)
* Update hello-world JS test (now also runs with node)
* feature-test WebAssembly in node instead
* Document that these options apply globally, and where
* Make sure hello-world.js output doesn't differ between mozjs/node
