Move label popup/selection support to SelectableLabel.
This is a platform-specific behaviour, and supporting it inside Label came at quite a high cost. Using Label in pannable areas is now a great deal cheaper (~10fps gained on qmlmail). This is technically an API-break, but research didn't find anyone actually using this API anyway.
