mk64f12: test failing with undefined reference to 'z_impl_sys_rand_get'

[manuargue]

Describe the bug
Tests failing with undefined reference to z_impl_sys_rand_get for boards hexiwear/mk64f12 and frdm_k64f/mk64f12. It looks like these boards lack of RNG driver and the test scenarios are not enabling any test RNG.

To Reproduce

west build -p -b hexiwear/mk64f12 tests/subsys/mgmt/mcumgr/os_mgmt_info -T mgmt.mcumgr.os.info.bt
west build -p -b frdm_k64f/mk64f12 samples/bluetooth/peripheral_ht -T sample.bluetooth.peripheral_ht.frdm_kw41z_shield
west build -p -b frdm_k64f/mk64f12 samples/bluetooth/peripheral_hr -T sample.bluetooth.peripheral_hr.frdm_kw41z_shield

Expected behavior
All tests above can build

Impact
Blocking CI of #82195 with unrelated failure

ninja: build stopped: subcommand failed.

Environment (please complete the following information):

• OS: Linux
• Toolchain Zephyr SDK 0.16.8
• Commit SHA or Version used: 6c7b38f

Additional context
Seems like a solution would be to enable CONFIG_TEST_RANDOM_GENERATOR=y either for the boards or in the test scenarios.

[hakehuang]

also impact NXP platforms with bluetooth shield #82390

[FRASTM]

also seen on stm32 nucleo_g070rb target when building samples/bluetooth/peripheral_hr/ --shield frdm_kw41z

[manuargue]

@jhedberg bumping prio from low to medium as this issue is affecting multiple boards

[erwango]

Failing CI here as well
