[0/2] Add new features for intel processor

This patchset is to add two new features for intel processors
which support them, like Sapphire Rapids. SERIALIZE is a faster
serializing instruction which does not modify registers,
arithmetic flags or memory, will not cause VM exit. TSX suspend
load tracking instruction aims to give a way to choose which
memory accesses do not need to be tracked in the TSX read set.
