QMimeDatabase: collect glob patterns from all locations

A QMimeTypePrivate used to belong to a single provider, which would
provide the complete data for it.
But since the redesign in commit 7a5644d6481a3c1a741677, each provider
represents is a single mime directory, and the merging happens at the
QMimeDatabase level. So we need a QMimeType[Private] to be just a name
(a "request" for information about this mimetype) and the information
for that mimetype is retrieved on demand by querying the providers
and either stopping at the first one (e.g. for icons) or merging
the data from all of them (e.g. for glob patterns).

The XML provider was using QMimeTypePrivate as data storage,
give it its own struct QMimeTypeXMLData for that purpose instead.
