QVLA: separate control from inline storage [1/N]: Extract Base Classes

In this first patch of the series, we move the fields (a, s, ptr) and
(array) into each their base class, separating concerns: The QVLABase
class is independent of Prealloc, while the QVLAStorage class is
independent of T (only depends on Prealloc, alignof(T) and sizeof(T),
and that can probably be reduced even further in later patches, since
we ought to need only alignof(T) and sizeof(T) * Prealloc, and
alignment can be substituted with std::max_align_t).

Doing so while keeping all member functions on QVLA, however, means we
need to sprinkle 'this->' in front of every data member access. C'est
la vie.
