As there is no need for a Prekernel on aarch64, the Prekernel code was moved into Kernel itself. The functionality remains the same. SERENITY_KERNEL_AND_INITRD in run.sh specifies a kernel and an inital ramdisk to be used by the emulator. This is needed because aarch64 does not need a Prekernel and the other ones do.
