Implement issue #10691359: Kill long-running processes
We now have the activity manager kill long-running processes
during idle maintanence.
This involved adding some more information to the activity manager
about the current memory state, so that it could know if it really
should bother killing anything. While doing this, I also improved
how we determine when memory is getting low by better ignoring cases
where processes are going away for other reasons (such as now idle
maintenance). We now won't raise our memory state if either a process
is going away because we wanted it gone for another reason or the
total number of processes is not decreasing.
The idle maintanence killing also uses new per-process information
about whether the process has ever gone into the cached state since
the last idle maintenance, and the initial pss and current pss size
over its run time.

Idle maintenance scheduling broken.
1. The scheduling was relying on receiving battery level broadcasts
which however are not sent if the device is asleep. The maintenance
window was not bound and we could miss a frame if the user did
not interact the device longer than the min time between two
maintenance windows.
2. Hide the idle maintenance intents since this will be rewritten
to user services.

Perform idle maintenance when the device is charging.
Added the precondition that the device should be charging to the
existing ones of the device not being used for awhile and the
battery level being high enough. Note that even if the device is
charging, we have to check the battery level since the user can
unplug it at any time.

Adding idle maintenance service.
It is beneficial that there is a mechanism on the platform
to notify applications whether it is safe to perform somehow
expensive operations while the user is not using the device.
Thus, user experience will not be degraded. An example is
discarding of unused blocks on a mounted file system instead
of doing this on every write operation.
