Summary SystemFontDatabase::m_systemFontShorthandCache may hold stale font metrics

Code analysis has uncovered a correctness issue that causes the SystemFontDatabase to retain stale font metrics after they are no longer needed. Since those entries consists of a string plus 8 bytes worth of size/weight data, this seems worth improving.
