Removing HOST_RUN_PLACEHOLDER for ESIMD Kernels

- Host backend and esimd_emulator backend share same header file for
memory intrinsic support - memory_intrin.h

- This sharing prevents the same header file from supporting both
backend types as some intrinsic support (e.g. __esimd_media_ld/st) are
different and they are chosen during kernel compilation - while
backends are chosen during kernel execution

- Therefore, tests invoking those implementations must not contain
'HOST_RUN_PLACEHOLDER' as the implementations require esimd_emulator
backend
