Add process capability as a new dimension.

Add new attribute capability to ProcessRecord, it represents what this
process is allowed to do. Capability is a separate dimension for
process state (ProcState).

In OomAdjuster.java, capabilities can be passed from client to service.

Add PROCESS_CAPABILITY_FOREGROUND_LOCATION to represent the capability
that can access location while-in-use.

For permission such as foreground location access, AppOpsService
checks for FOREGROUND_LOCATION capability, also checks if the process
is in one of the foreground process states, if both conditions meet,
the locaton operation is allowed.

Remove PROCESS_STATE_FOREGROUND_SERVICE_LOCATION.
