Subject: [PATCH] QTzTimeZoneCache: make findEntry() static

It doesn't need access to the members, so making it static both saves
the implicit this pointer, and communicates to the reader that this is
function doesn't access other QTzTimeZoneCache members.

In particular, it proves that it doesn't really need to be called with
m_mutex locked, cf. QTBUG-122138.

Task-number: QTBUG-122138
Pick-to: 6.7 6.6 6.5
