The documentation for PROT_MTE says that it cannot be cleared by mprotect. Further, the implementation of the VM_ARCH_CLEAR bit, contains PROT_BTI confiming that bit should be cleared. Introduce PAGE_TARGET_STICKY to allow target/arch/cpu.h to control which bits may be reset during page_set_flags. This is sort of the opposite of VM_ARCH_CLEAR, but works better with qemu's PAGE_* bits that are separate from PROT_* bits.
