system: Allow restricting the legacy cpu_ld/st() 'native-endian' API

Guard the native endian APIs we want to remove by surrounding
them with TARGET_NOT_USING_LEGACY_NATIVE_ENDIAN_API #ifdef'ry.

Once a target gets cleaned we'll set the definition in the
target config, then the target won't be able to use the legacy
API anymore.
