chore: Remove ReanimatedError and WorkletsError from global types (#8435)

## Summary

This PR removes `ReanimatedError` and `WorkletsError` types from
`privateGlobals.d.ts` type declarations. I decided to remove them as it
was very confusing that TS wasn't complaining when these error
constructors were called without importing them but the missing import
resulted in the runtime crashes.

## Examples

### Before

Allowed to use `ReanimatedError` without the necessary import.

/> |

#### Without import in tests

/>

### After

Properly shows that the `ReanimatedError` is not imported if there is no
import.
