Try to get rid of warnings in Java2Swift generated sources: generics

[ktoso]

We have a lot of noise thanks to these:

 98 | extension TreeMap {
 99 |   @JavaClass("java.util.AbstractMap$SimpleImmutableEntry")
100 |   open class SimpleImmutableEntry<K: AnyJavaObject, V: AnyJavaObject>: JavaObject {
    |                                                     `- warning: generic parameter 'V' shadows generic parameter from outer scope with the same name; this is an error in the Swift 6 language mode

it'd be nice to avoid them, e.g. make those V1 or something

Hi @ktoso,
Could you point me to which file I should implement this change inside?

Most of this is in JavaTranslator however some of it may be spread around that Java2SwiftLib module.

We should somehow keep track that a V is already used in an outer scope and then use a V1 for example or different name
