perf: Add new macros for mem_hops field
Add new macros for mem_hops field which can be used to
represent remote-node, socket and board level details.
Currently the code had macro for HOPS_0, which corresponds
to data coming from another core but same node.
Add new macros for HOPS_1 to HOPS_3 to represent
remote-node, socket and board level data.
For ex: Encodings for mem_hops fields with L2 cache:
L2 - local L2
L2 | REMOTE | HOPS_0 - remote core, same node L2
L2 | REMOTE | HOPS_1 - remote node, same socket L2
L2 | REMOTE | HOPS_2 - remote socket, same board L2
L2 | REMOTE | HOPS_3 - remote board L2
