Change dump-classes profman option to dump-classes-and-methods

The new option is called "--dump-classes-and-methods". This option
dumps methods and classes in the profile as a format that is valid
input for the "--create-profile-from" option.

The goal is to be able to store text based profiles that don't
depend on dex indices or checksums.
