Fix build of Core module without regularexpression feature

qregularexpression.h requires FEATURE_regularexpression to be enabled.
Add a condition to the 'qt_pch.h' header to fix the build when PCH
are enabled and FEATURE_regularexpression is disabled.

It seems that the filter implementation of QSortFilterProxyModel
has QRegularExpression as its base. It's necessary to make
sortfilterproxymodel dependent on the regularexpression feature.

Fix the precompiler condition for the extractSections function in
the QString implementation. Use the same precompiler condition for
the QString::section and extractSections functions, since
QString::section depends on extractSections.
