QFileSystemModel sort extremely inefficient with wildcards

Hello,

Consider the function

bool QFileSystemModelPrivate::filtersAcceptsNode(const QFileSystemNode *node) const

which is called for every child in sortChildren:

https://github.com/qt/qtbase/blob/dev/src/gui/itemmodels/qfilesystemmodel.cpp#L2158

It will call most of the time

bool QFileSystemModelPrivate::passNameFilters(const QFileSystemNode *node) const

which, for every wildcard name filter given to the model, constructs a QRegularExpression, and compiles it !

https://github.com/qt/qtbase/blob/dev/src/gui/itemmodels/qfilesystemmodel.cpp#L2158

In my use case I have a fair amount of wildcards, coming from plug-ins to my software which make some file extensions visible or not in a QFSModel. When sorting a hundred files, this blocks the software for 4/5 seconds every time.
