QFileDialog: add MIME Type filters

Currently just a convenience method for setNameFilters(), it uses
QMimeType to create a name filter from the glob patterns and
description defined in each MIME type.

In the longer term, this API could be used to do proper mimetype-based
filtering using QMimeDatabase::mimeTypeForFile() in the builtin
QFileDialog (aka "not native"), instead of only looking at globs via the
name filters.
