boundType does not appear to support Any

[matejdro]

This piece of code:

@ContributesMultibinding(ActivityInjection::class, boundType = Any::class)
class TestViewModel @Inject constructor() : SimpleStackViewModel() {
...
}

Will throw an error:

TestViewModel contributes a binding for kotlin.Any, but doesn't extend this type.

Obviously, this class DOES extend Any.

This worked in Anvil 2.3.4 but it's now broken in 2.4.1.

Setting bound type to the SimpleStackViewModel works, so it appears just using Any as a boundType is an issue.
