Subject: Add optimize, shrink level and debug info options to C/JS (#1357)

* 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
