This commit simplifies OS <-> Application interface controlling power
management. In the previous approach application-based PM required
overriding sys_suspend() and sys_resume() functions. As these functions
actually implemented power state change, in such case application
basically had to provide own implementation of all PM-related stuff,
which was not portable and hard to maintain.
This commit changes this scheme: The sys_suspend() and sys_resume()
are now system functions while the application could either use
built-in power management policies or provide its own. All details
of power mode switching are now handled by the OS.
Also, this commit cleans up the Kconfig options related to system-level
power management grouping them under common CONFIG_SYS_PM_ prefix.

The SYS_POWER_LOW_POWER_STATE_SUPPORTED and SYS_POWER_LOW_POWER_STATE
suggests one low power state but these options control multiple
low power state. This commit uses plural in the names to indicate
that.

This patch modifies Kconfig dependencies to ensure System Power
Management option selects Tickless Idle one.

* because stack analysis is required, so STACK_CHECK must be
turned off. No HW_STACK_PROTECTION has no impact on current test
* If CONIFG_USERSPACE, the real stack size is bigger than the declared
stack size
