This commit introduce 'USE_SWITCH' feature into cortex-A/R(aarch32) architecture For introducing USE_SWITCH, the exception entry and exit are unified via `z_arm_cortex_ar_enter_exc` and `z_arm_cortex_ar_exit_exc`. All exceptions including ISR are using this way to enter and exit exception handler. Differentiate exception depth and interrupt depth. Allow doing context switch when exception depth greater than 1 but not allow doing this when interrupt depth greater than 1. Currently, USE_SWITCH doesn't support FPU_SHARING and USERSPACE.
