ice: xsk: Improve AF_XDP ZC Tx and use batching API

Browse source

Apply the logic that was done for regular XDP from commit 9610bd988d
("ice: optimize XDP_TX workloads") to the ZC side of the driver. On top
of that, introduce batching to Tx that is inspired by i40e's
implementation with adjustments to the cleaning logic - take into the
account NAPI budget in ice_clean_xdp_irq_zc().

Separating the stats structs onto separate cache lines seemed to improve
the performance.
