Introduce flags to indicate the QArrayData type

These flags allow us to determine what type of data QArrayData is
carrying. There are currently only two supported types:
 - raw data type: constructed via fromRawData or static data
 - allocated data type: regular data done via heap allocation

The QArrayData object is usually allocated on the heap, unless its own
reference count is -1 (indicating static const QArrayData). Such
object should have a type of RawDataType, since we can't call free().

Add GrowsBackward for completeness as well as the StaticDataFlags
default for static data.
