Add an emulation flag X86EMUL_F_INVLPG, which is used to identify an instruction that does TLB invalidation without true memory access. Only invlpg & invlpga implemented in emulator belong to this kind. invlpga doesn't need additional information for emulation. Just pass the flag to em_invlpg(). Linear Address Masking (LAM) and Linear Address Space Separation (LASS) don't apply to addresses that are inputs to TLB invalidation. The flag will be consumed to support LAM/LASS virtualization.
