target/arm: Define arm_cpu_do_unaligned_access for user-only
Use the same code as system mode, so that we generate the same
exception + syndrome for the unaligned access.
For the moment, if MTE is enabled so that this path is reachable,
this would generate a SIGSEGV in the user-only cpu_loop. Decoding
the syndrome to produce the proper SIGBUS will be done later.
