metric: Add net_rx action statistic to network performance metric
The net_rx_action is the bottom-half function used to process NIC incoming
frames. The patch calclates net_rx action statistic in the trace to get
count, runtime and distrubiton on each core and further to get interstack
latency (Time for a packet move through the kernel protocol stack).
