Rename namespace QtMultimedia::MetaData -> QMediaMetaData

Main code, examples, tests and docs updated. Method:
1. Remove unused forward-declarations, "class QMediaMetaData"
2. Mass find+replace "QtMultimedia::MetaData" -> "QMediaMetaData"
3. Un-nest from the QtMultimedia namespace in qtmedianamespace.h

For consistency (with minimal disruption), namespaces with a "Qt" prefix
will be renamed. Also, Qt guidelines don't include nested namespaces
