core: panic: allow core halting on SGI in other cases than panic()

There may be cases where we want to halt several cores outside of a

Therefore, add CFG_MULTI_CORE_HALTING switch that allows to register
an interrupt handler for the CFG_HALT_CORES_SGI that is dedicated to
halt other cores.

This reduces the scope of CFG_HALT_CORES_ON_PANIC that is now used only
for halting other cores in a panic() sequence.
