Update QuotaExceededError usage

QuotaExceededError is graduating from being a DOMException name into a new error class, in whatwg/webidl#1465. Update creation sites to reflect this.

For now, the quota and requested properties are left at their default (null). Future work could include setting them in an informative fashion.
