Move the QMediaMetaData namespace into new files, and have sync.profile
generate the camel-case header during compilation.
For now, the new header (qmediametadata.h) is included whereever the old
one appears (qtmedianamespace.h), but an audit will be done later to
make explicit #includes only where necessary.
NOTE: Git may think that a rename has occurred.
