Subject: Rename QArrayData::AllocateOptions enum and update some flags

Rename to QArrayData::ArrayOptions in preparation for these flags
being in the array itself, instead of used just for allocating new
ones.

For that reason, rename QArrayData::Default to
DefaultAllocationFlags. And introduce QArray::DefaultRawFlags to mean
the flags needed for creating a raw (static) QArrayData.

Also rename QArrayData::Grow to GrowsForward, so we may add
GrowsBackward in the future.
