Use the profiles in the APEX to dexpreopt system server jars.

After this change, if "profile_guided: true" is set, profile-guided
compilation will be enabled for the jar and the ".prof" file next to
the jar in the APEX ("javalib/<name>.jar.prof") will be used as the
profile when dexpreopting for the prebuilt APEX.
