feat: add support for globalThis in event handling functions

[THernandez03]

What: Add GlobalThis to the event type definitions for fireEvent and createEvent.

Why: globalThis is a valid event target (it references window in browser environments), but the current type definitions don't accept it. This causes false type errors when firing or creating events on globalThis.

How:

• Added GlobalThis to the union types in FireFunction, FireObject, CreateFunction, and CreateObject in types/events.d.ts.
• Added type tests in types/__tests__/type-tests.ts to validate globalThis is accepted by fireEvent and createEvent.

Checklist:

• Documentation added to the
  docs site N/A
• Tests
• TypeScript definitions updated
• Ready to be merged
