fix(cli/rt/main): Add global interface objects

[nayeemrmn]

• Window
• DedicatedWorkerGlobalScope
• WorkerGlobalScope

---

Matches browsers.

Window globalThis prototype chain: Window -> EventTarget -> Object.
Worker globalThis prototype chain: DedicatedWorkerGlobalScope -> WorkerGlobalScope -> EventTarget -> Object.

console.log(globalThis);

// Before:
// { ... }

// After:
// Window { ... }

Use the following to detect a web worker environment:

if (globalThis.WorkerGlobalScope && globalThis instanceof WorkerGlobalScope) {
  // ...
}

LGTM

I hate weak inequality operator, and thought we had a linting rule to enforce it, but it seems we have a mixture of weak and strong equality/inequality in the code base so, 🤷‍♂️.
