Preopt APEX system server jars.

Browse Source 
The path to the artifacts will in the form of
/system/framework/oat/<arch>/<encoded-jar-path>@classes.{odex,vdex,art},
where <encoded-jar-path> is the path to the jar file with "/" replaced
by "@". For example,
/system/framework/oat/x86_64/apex@com.android.art@javalib@service-art.jar@classes.odex

There will be a follow-up CL to update ART runtime to recognize
artifacts in that path.

Test: m com.android.art
