Move from using profile-classes to art-profile

art-profile contains methods as well as classes. This will enable
possibly using speed-profile in the future.

Reduces services.art size from 700k -> 233k since it only includes
startup classes now (marlin).

Post boot vdex PSS on marlin goes from 6644k -> 6580k. TODO: Investigate
why this doesn't go down more.

Bug: 62356545
Test: make and flash
