Add reflective annotation box to support defaults in KSP

KSP cannot always read default values in annotations. This CL introduces
a new XAnnotationBox implementation that uses reflection instead to
workaround it.
Unfortunately, KSP's behavior does not let us distinguish between null
vs default or empty array vs default. In both cases, we prefer going to
the default value in the annotation if value is required.

Also added support for enum lists in the java annotation box
implementation.
