boot/zephyr: Move RAM load Kconfigs outside !SINGLE_APPLICATION_SLOT

Now that RAM load code is not dependent on bootutil/loader.c, it can be
used independently of !SINGLE_APPLICATION_SLOT configurations. Move the
related Kconfigs accordingly, so that applications configured to use
single loader can do RAM loading.
