QQuickTableView: remove cacheBuffer from the public API

As discussed during API review, remove cacheBuffer from the public API.
The cache buffer was a feature inherited from ListView to avoid loading
a lot of items (and affect performance) when the user started to flick.
But now that TableView has support for reusing items, the point of the
cache buffer is more or less gone. At least we choose to remove it from
the public API until we have better understanding if this is really needed.

Note that the cacheBuffer still plays a small role internally, so we
don't remove it from the implementation. We want to preload an extra row
and column for reuse at start-up, since you often cannot reuse the first
row and column during the first flick (they will still be visible
on the screen).
