common/qat: add new GEN3 device

Added new GEN3 QAT device ID.
This device has a wireless slice, but other GEN3 devices do not,
so we must set a flag to indicate this wireless enabled device.

Capabilities for the device are slightly different from base GEN3
capabilities, some are removed from the list for this device.

Symmetric, asymmetric and compression services are enabled.

compress/qat: support IM buffer too small operation

This patch implements a special way of buffer handling when internal
QAT IM buffer is too small for Huffman dynamic compression operation.
Instead of falling back to fixed compression, the operation is now
split into multiple smaller dynamic compression requests (possible to
execute on QAT) and their results are then combined and copied into
the output buffer. This is not possible if any checksum calculation
was requested - in such case the code falls back to fixed compression
as before.

common/qat: support dual threads for enqueue/dequeue

Remove the limitation whereby enqueue and dequeue must be
done in same thread.
The inflight calculation is reworked to be thread-safe for 2
threads - note this is not general multi-thread support, i.e
all enqueues to a qp must still be done in one thread and
all dequeues must be done in one thread, but enqueues and
dequeues may be in separate threads.
Documentation updated.
