K2: resolve remove(Int) clash in JavaOverrideChecker

In Kotlin subclasses of `MutableCollection<Int>`, the method
`remove(Int)` has its argument boxed, so that it wouldn't clash with the
method from `java.util.List`. So `JavaOverrideChecker` should understand
that a Java method `boolean remove(java.lang.Integer)` overrides it,
otherwise platform declaration clash was reported.

The code is adapted from `forceSingleValueParameterBoxing` in K1's
`methodSignatureMapping.kt`.

The test has been moved and adapted from diagnostic to codegen box
tests, to check correct backend execution + runtime.
