Replace QArrayData::capacityReserved with a full flags field
Instead of stealing one bit from the alloc field, let's use a full
32-bit for the flags. The first flag to be in the field is the
CapacityReserved (even though the allocate() function will store some
others there, not relevant for now).
This is done in preparation for the need for more flags necessary
anyway.
