Add defines for the architectural memory types that can be shoved into various MSRs and registers, e.g. MTRRs, PAT, VMX capabilities MSRs, EPTPs, etc. While most MSRs/registers support only a subset of all memory types, the values themselves are architectural and identical across all users. Leave the goofy MTRR_TYPE_* definitions as-is since they are in a uapi header, but add compile-time assertions to connect the dots (and sanity check that the msr-index.h values didn't get fat-fingered). Keep the VMX_EPTP_MT_* defines so that it's slightly more obvious that the EPTP holds a single memory type in 3 of its 64 bits; those bits just happen to be 2:0, i.e. don't need to be shifted. Opportunistically use X86_MEMTYPE_WB instead of an open coded '6' in setup_vmcs_config(). No functional change intended.
