[test-point] Implement chip_sw_csrng_edn_cmd
The chip_sw_entropy_src_csrng test is updated to check for edn command
done irqs in addition to csrng entropy request irqs. A generate command
is sent using the EDN SW_CMD_REQ register to generate enough entropy for
the otbn randomness test. The otbn randomness test is used to check the
EDN output.
