Add a QMetaSequence interface

This is in line with QMetaType and will be used to implement a mutable
QSequentialIterable. Later on, a QMetaAssociation will be added as
well, to implement a mutable QAssociativeIterable.

The code here represents the minimal set of functionality needed to have
a practical sequential container. The functionality is not completely
orthogonal. In particular, the index based operations could be
implemented in terms of iterator-based operations.
