QmlJS: Scan app.qmltypes and lib.qmltypes for type information

app.qmltypes is being added as a new convention to Qt 5.15. These files
are to be found next to application binaries, and contain the QML types
those application register themselves, in contrast to QML types
registered from plugins loaded via the regular import mechanism.

lib.qmltypes works the same way, in principle, for libraries. This
change only adds it to the possible names for qmltypes files, though.
