There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.
To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

This commit changes the names of SYS_POWER_DEEP_SLEEP* Kconfig
options in order to match SYS_POWER_LOW_POWER_STATE* naming
scheme.

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.

System Power Management is only supported in Tickless Idle mode.
This patch modifies Kconfig dependencies to ensure System Power
Management option selects Tickless Idle one.
Fixes: #11046

Removed redundant and unused config options from conf files.
Added separate files for handing power management and device
handling functions.
Added the PM policy based on the next timeout event instead of
simply advancing to the next power state.

This sample tesecase provides sample code :-
1. Triggers Low Power tasks into nrf52 SOC (CONST LAT and LOW PWR)
2. Triggers System Off state.
3. Wake up device through port Event by GPIO (Button 1).
