7b9978883c arch/arm: optimize context switch speed 
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

It was separate because the syscal handler was using it before calling
_xtensa_context_save.  The order of operations has now changed and we
can save A3 with the rest of the context.
