net: hns3: add getting capabilities of gro offload and fd from firmware
As some new devices may not support GRO offload and flow table director,
to support these devices, driver needs to querying capabilities of GRO
offload and flow table director from firmware. Whether the driver
supports these two features depends on capabilities.
For old device of version HNAE3_DEVICE_VERSION_V2, driver sets their
capabilities of these two features to fixed value.
Setting default features of netdev and debugfs also need to identify
whether support these two features.
