net: hns3: create new set of common tqp stats APIs for PF and VF reuse

This patch creates new set of common tqp stats structures and APIs for PF
and VF tqp stats module. Subfunctions such as get tqp stats, update tqp
stats and reset tqp stats are inclued in this patch.

These new common tqp stats APIs will be used to replace the old PF and VF
tqp stats APIs in next patches.
