Update to latest qml CMake API

The new qml CMake API places a closer relationship between
the backing target and the plugin target. Both are typically
created together and they share a lot of common details.
Instead of creating them in different parts of the source
tree, they are now specified together. The src/imports
area has effectively been absorbed into the other
corresponding subdirectories below src with this change.
