Add JavaAPI stubs for missing java.lang.reflect and java.io types; remove author tags

[shai-almog]

Motivation

• The BytecodeTranslator emitted "no class definition" errors for reflection-related types and java.io.Externalizable during translation, causing downstream iOS build steps to fail.
• Providing minimal Java API stubs allows the translator to resolve these referenced types during writeOutput so classes are not purged or translation does not fail.
• A missing xcodebuild in CI PATH is an environment/configuration issue that must be investigated separately and is not addressed by these stubs.

Description

• Added stub interfaces under vm/JavaAPI/src/java/lang/reflect: GenericArrayType, ParameterizedType, TypeVariable, and WildcardType.
• Added IO-related stubs under vm/JavaAPI/src/java/io: Externalizable, ObjectInput, and ObjectOutput.
• Removed author tags from the new stub files to match repository style.

Testing

• No automated tests were executed for this change.
