cpu/cortexm_common: allow to overwrite nmi_handler
...
If a user wants to handle NMI events, let them do so by
providing an implementation for nmi_handler() instead of
paniking.

cpu/cortexm_common: remove breakpoint from hard_fault_handler
...
The hard fault handler would normally call core_panic() which in turn
calls ps() - this already helps debugging a lot of crashes caused by
a thread stack overflow.
With the breakpoint in place, the code will not advance to this, leaving
users unknown of this feature in the dark.
On top, the breakpoint is not very helpful if thread stacks are already
corrupted.
Let's just drop it for simplicity's sake - it's not there for any other
architectures.

reference platforms (native, M3) have been established well.

makefiles/kconfig: use two lists for boards and CPUs default configs
...
This introduces KCONFIG_BOARD_CONFIG and KCONFIG_CPU_CONFIG variable for
boards and CPUs (including common directories) to add default
configuration files to be merged. The current approach, as it uses
Makefile.features, would include boards first, not allowing them to
override CPU configurations.

The global core/ldscripts/xfa.ld doesn't match our cortexm_base.ld.
This commit directly adds the two XFA lines to cortexm_base.ld.
In addition to that, a dummy (empty) xfa.ld is added, which the linker will pick
instead of core/ldscripts/xfa.ld, effectingly not using it.

The bit access functions are not tied to Cortex-M CPUs, here they only
provide optimisations via bit-banding.
But the functions are generally useful - so move them to an arch independent
location.
