tests: arch: common: ramfunc: add nrf54h20pdk cpuapp overlays

On nRF54H20, we need to configure RAM with execution permissions in
order to execute code from it. This patch adds overlays for the nRF54H20
PDK cpuapp cores so that RAM0X region is given execution permissions and
so the test runs successfully.
