QMetaType: Add a benchmark covering creation of QVariant from an enum

Browse Source 
This proved to be quite slow in the past due to QReadWriteLock's implementation
being suboptimal (prior to its improvement in
343e5d066a6b5583688e16baec20f20e6d9a24e0).

This codepath is exercised quite extensively by QML with enum registrations.
