Variance is missing after asMemberOf call

[kuanyingchou]

This is a KSP1 issue. When a Java field is of a generic Kotlin type with declaration site variance, its wildcard is lost after asMemberOf call. For example, the type of the field A<? extends Number> a; becomes (A<(Number..Number?)>..A<(Number..Number?)>?) instead of (A<out (Number..Number?)>..A<out (Number..Number?)>?), where A is defined as interface A<out T>.
