- Move PM related APIs to `include/pm` so that it follows API `pm_`
prefix namespace. In order to make transition easier
`include/power/power.h` is kept pointing to `include/pm/pm.h`.
- Move most of device PM related content from `include/device.h` to
`include/pm/device.h` and `include/pm/runtime.h`.

Create a separate sub group for constraint APIs. This way it is
possible to reference this api directly in the power management
reference without mess with the rest of the documentation.

New power states have more granularity than deep sleep and sleep
states. Just get rid of this and keep the same behavior for now.

pm_system_resume_from_deep_sleep is not implemented or used
anywhere. Just remove it and keep the code base cleaner.

This function is useless and the state variable that it was
controlling is also not necessary because the same logic is being
handled by the variable post_ops_done.\
This reasonably simplifies idle thread logic.

pm_power_state_force had two different behavior, if
CONFIG_PM_DIRECT_FORCE_MODE was enabled this function immediately
calls pm_system_suspend() without wait the idle thread. Without this
option enabled, this function will wait for the idle thread run but
will use the given power state instead of asking the policy manager.
The problem in both cases is that the process involves handling
devices and the way that was implemented if at least one device failed
to go to low power or suspended the system power state would not
change / be forced.
This commit simplifies this API removing the conditional behavior
since it is not clear the need for that and effectively, and
immediately, forces the system to go to the given state without
bother with devices.

pm_system_suspend is called only from the idle thread and should
not be exported as a public API.

- Remove SYS_ prefix
- shorten POWER_MANAGEMENT to just PM
- DEVICE_POWER_MANAGEMENT -> PM_DEVICE
and use PM_ as the prefix for all PM related Kconfigs

Add system power management direct force trigger mode. In this
mode application thread can directly put system in sleep or deep
sleep mode instead of waiting for idle thread to do it, so that
it can reduce latency to enter low power mode.

move power.h to power/power.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
