Merge lang/qt5-qml and x11-toolkits/qt5-qml into x11-toolkits/qt5-declarative

Summary

We are splitting that package for no obvious reason or benefit, as most of the ports that depend on one also depend on the other.

[tcberner]

Remove components for qml and quick.

[tcberner]

The chances of this being reviewed are slim, so I'll just ask for an exp-run :D, while having reviewd it as kde@-hatter. Surely, that holds up in court ^^

[tcberner]

Close.
