Define independent macros for the RWX protection bits that are enumerated via EXIT_QUALIFICATION for EPT Violations, and tie them to the RWX bits in EPT entries via compile-time asserts. Piggybacking the EPTE defines works for now, but it creates holes in the EPT_VIOLATION_xxx macros and will cause headaches if/when KVM emulates Mode-Based Execution (MBEC), or any other features that introduces additional protection information. Opportunistically rename EPT_VIOLATION_RWX_MASK to EPT_VIOLATION_PROT_MASK so that it doesn't become stale if/when MBEC support is added. No functional change intended.
