Richard Henderson 7f2cf760fe linux-user/aarch64: Do not clear PROT_MTE on mprotect 
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.
