qmllint: Properly process qmldir imports and dependencies

We don't want to pick the dependencies from the qmltypes files. Rather,
parse them directly from the qmldir. Do process versions, too.

Also, import explicitly given qmltypes files only once, and don't expose
QML types from dependencies as actual types. Hide them behind an
inaccessible prefix.

For the inaccessible prefix to work, we need to import the C++ class
names without the prefix. The prefix doesn't make sense for C++ names
anyway.

In addition, properly process version-less imports.
