ae9ef972c0 paging: Rename existing CONFIG_PAGING to CONFIG_LEGACY_PAGING 
Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.

On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.

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.
