Remove getGlobalObject usage from utils (#5831)

-  Replaces  `getGlobalObject` with a const `GLOBAL_OBJ` 
   - Improvement over before since we only evaluate the detection code once
   - No need to lazily evaluate since `GLOBAL_OBJ` is always accessed
- Also includes a `WINDOW` const which returns `GLOBAL_OBJ` but with `typeof GLOBAL_OBJ & Window` type.
   - This will eventually move to `@sentry/browser` to ensure stricter typing around the global object
