Correct return type of QXmlQueryPrivate::staticContext()
As reported by UBSan:
qtbase/src/corelib/tools/qshareddata.h:167:13: runtime error: downcast of address 0x2ac9a801a410 which does not point to an object of type 'GenericStaticContext'
0x2ac9a801a410: note: object is of type 'QPatternist::StaticFocusContext'

^~~~~~~~~~~~~~~~~~~~~~~
vptr for 'QPatternist::StaticFocusContext'
I had no idea how the QExplicitlySharedDataPointer conversion
could ever compile, until I saw that this module defines
QT_ENABLE_QEXPLICITLYSHAREDDATAPOINTER_STATICCAST
which is, of course, utterly broken.
