linux-user: Explicitly untag memory management syscalls
We define target_mmap et al as untagged, so that they can be
used from the binary loaders. Explicitly call cpu_untagged_addr
for munmap, mprotect, mremap syscall entry points.
Add a few comments for the syscalls that are exempted by the
kernel's tagged-address-abi.rst.
