[GR-47881] [GR-59369] Drop total types/fields/methods from build output.

[graalvmbot]

Also, deprecate these metrics in the build-output-schema and remove already deprecated metrics.

The total numbers reported for types, fields, and methods are misleading. They are not the total numbers across the whole application. They are only the total numbers of types, fields, and methods loaded by the class loaders. And because class loading is non-deterministic, these numbers are not always the same across builds of the same application. Since the number of loaded types, fields, and methods has very little meaning to users, we are removing them and simplifying the build output.
