Auto-generate docs based on annotations.
We have a handful of annotations that we've been sprinkling across
the platform APIs, such as @Nullable, @NonNull, @IntDef, etc. It
would be really helpful to surface these contracts to developers
through the SDK docs.
This change allows annotations like those mentioned above to declare
the following new javadoc fields:
@memberDoc: docs to append to a field or method definition.
@paramDoc: docs to append to a @param definition.
@returnDoc: docs to append to a @return definition.
This change also builds a docstring to describe the list of all
constants listed in an @IntDef annotation. Sadly AnnotationDesc
only passes along raw constant values, so we need the help of the
new "prefix" annotation argument to help find the field names.
Test: builds
