  A new flag RTE_CPUFLAG_MONITORX is added to rte_cpu_flag_t in
DPDK 23.07 release to support monitorx instruction on EPYC processors.
This results in ABI breakage for legacy apps.

mwaitx allows EPYC processors to enter a implementation dependent
power/performance optimized state (C1 state) for a specific period
or until a store to the monitored address range.
