[ksp2] Annotation value vararg is handled as single item (in java source file only)

[acejingbo]

For an annotation

@interface MyAnnotation2 {
    String[] value() default {"3", "5", "7"};
}

If you do @MyAnnotation2("4") in java library, kotlin library, or kotlin source file, KSP2 will consider value to be an string array ["4"] correctly
But in java source file, KSP2 will consider it an single item "4"

See test fail for MyClass.java because value should be [4] but is 4, but it does not fail for MyClassKotlin.kt and MyClassInLib.java
