cpu: Directly use get_memory_mapping() fallback handlers in place

No code uses CPUClass::get_memory_mapping() outside of hw/core/cpu.c:

  $ git grep -F -- '->get_memory_mapping'
  hw/core/cpu.c:87:    cc->get_memory_mapping(cpu, list, errp);
  hw/core/cpu.c:439:    k->get_memory_mapping = cpu_common_get_memory_mapping;
  target/i386/cpu.c:7422:    cc->get_memory_mapping = x86_cpu_get_memory_mapping;

Check the handler presence in place and remove the common fallback code.
