Add ExecStorePinnedBufferHeapTuple.

This allows to avoid an unnecessary pin/unpin cycle when storing a
tuple in an already pinned buffer into a slot, when the pin isn't
further needed at the call site.

Only a single caller for now (to ensure coverage), but upcoming
patches will increase use of the new function.
