tests: arch: arm: add a test for fatal errors in interrupts This commit adds a new test suite in tests/arch/arm that intends to testing system faults inside interrupts. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no>

Title: Test to verify code fault handling in ISR execution context (ARM Only)
Description:
This test verifies that we can handle system fault conditions
while running in handler mode (i.e. in an ISR). Only for ARM
Cortex-M targets.
---------------------------------------------------------------------------
Building and Running Project:
This project outputs to the console. It can be built and executed on QEMU as
follows:
ninja/make run
---------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
ninja/make clean # discard results of previous builds
# but keep existing configuration info
or
ninja/make pristine # discard results of previous builds
# and restore pre-defined configuration info
---------------------------------------------------------------------------

kernel: rename z_arch_ to arch_ Promote the private z_arch_* namespace, which specifies the interface between the core kernel and the architecture code, to a new top-level namespace named arch_*. This allows our documentation generation to create online documentation for this set of interfaces, and this set of interfaces is worth treating in a more formal way anyway.
