[BOLT] Attach ORC info to instructions in CFG

Propagate Linux Kernel ORC information read from the file to the whole
function CFG once the graph has been built. We have a choice to either
attach ORC state annotation to every instruction, or to the first
instruction in the basic block to conserve processing memory. I chose to
attach to every instruction under --print-orc option which is currently
on by default.

Depends on D155153, D154815
