Feature: implement ticket spinlock

Browse Source 
test config: ./tools/configure.sh -l qemu-armv8a:nsh_smp

Pass ostest

No matter big-endian or little-endian, ticket spinlock only check the
next and the owner is equal or not.

If they are equal, it means there is a task hold the lock or lock is
free.
