Add ART profile to Connectivity service.

This CL adds an ART profile to the Connectivity service. The profile was
generated by profiling the Connectivity service on Droidfood population.

The ART profile is expected to reduce the size of the Connectivity
service generated code size by 3.9MB!

Background: A profile is a list of classes and methods that are
frequently used, which ART uses to compile parts of the code ahead of
time, and the rest of the code can be interpreted and Jitted on the fly
if needed, this improves app-startup, memory and disk space
significantly!

For system server modules (like Connectivity), the current behavoir is
to Speed compile (compile everything), which for sure compiles
unnecessary code. By moving the speed-profile mode we are saving around
3.9MB of disk space which also decreases the load on memory!

The new behavior is guarded by a new build feature
`RELEASE_ART_COMPILE_CONNECTIVITY_SERVICE_SPEED_PROFILE`
