[rv_core_ibex, top_earlgrey] Enable SecureIbex for CW340

As the `SecureIbex` configuration is the one we use for the Earl Grey ASIC, we also should enable it for the FPGA boards. Due to resource constraints, this is only possible for the CW340 but not the CW310. Resource utilization stays still will below 70%. Closes #25137 Signed-off-by: Pascal Nasahl <[email protected]>
