arm64: memtag: strip tag from crash dumps

The MTE tag is not really useful when displaying a crash dump. In fact
it makes it more complicated for tools like script/symbolize.py to
retrieve the actual (untagged) virtual address, especially as we now
support non-Arm architectures and therefore blindly stripping the MTE
bits is not possible.

This commit strips the tag in call stacks displayed by
print_stack_arm64(). It also removes it from the virtual address shown
on abort (__print_abort_info()) since symbolize.py does try to resolve
the address as symbol + offset ; but in this case the tagged address is
printed as well, because it can be helpful to diagnose tag check faults.
