arch: arm: BusFault, NMI, and HardFault in Secure state when in test

Browse source 
This commit enables the option to route the BusFault,
HardFault, and NMI exceptions in Secure state, when
building for Cortex-M CPUs with ARM_SECURE_FIRMWARE=y.
This allows the various test to utilize BusFault,
HardFault and NMI exceptions during testing.

ARM Cortex-M configuration required when testing.
Currently, this option is only utilized, to force routing
BusFault, HardFault, and NMI exceptions to Secure State,
when building a Secure ARMv8-M firmware. This will allow
the testing suite to utilize these exceptions, in tests.
Note that by default, when building with ARM_SECURE_FIRMWARE
set, these exceptions are set to target the Non-Secure state.
