Add SystemInterface API to collect the list of processes running on the system.
This API will return a list of (PID, UID) for each process it sees running at the time it is invoked.
The list is gathered by scavenging /proc, and should be treated as an instantaneous snapshot.
There is potential for security vulns associated with /proc access. For this reason, Android defaults
to mounting /proc hidepid=2,gid=readproc, in order to minimize and control the portions of the system
that can gain unrestricted access.
In order to play along with this requirement, the implementation of getRunningProcesses() is backed by
a native service, which has a surface area much smaller than CarService, and access is restricted to
SYSTEM and ROOT users only.

Refactor SystemInterface.
Split SystemInterface into a set of smaller chunks, each wrapping one specific functional set of system APIs.
Provide default implementations of each of those chunks.
Rework SystemInterface to be a class that wraps all the chunks and forwards to each of them.
Add a Builder API to allow one to construct a full SystemInterface from individual chunks.
This turns a fairly heavy-weight interface into smaller pieces which are easier to use individually, and it also makes
it easier for tests to only change a subset of SystemInterface functionality when they need to do so.
