perf c2c report: Add 'node' sort key

Browse source

It is to be displayed in the single cacheline output:

  node

It displays nodes hits related to cacheline accesses.

The node filed comes in 3 flavors:
  - node IDs separated by ','
  - node IDs with stats for each ID, in following format:
      Node{cpus %hitms %stores}
  - node IDs with list of affected CPUs in following format:
      Node{cpu list}

User can switch the flavor with -N option (-NN,-NNN).
It will be available in TUI to switch this with 'n' key.
