Compiler crash when ContributesBinding boundType has type parameters

[eygraber]

If I have an interface with type parameters:

interface Foo<T, R>

and I use ContributesBinding on a concrete implementation of it:

class Bar
class Baz

@ContributesBinding(MyScope::class)
class RealFoo : Foo<Bar, Baz>

I get the following crash:

[ksp] java.lang.IllegalStateException: KSType 'Foo<Bar, Baz>' has type arguments, which are not supported for ClassName conversion. Use KSType.toTypeName().

We should make this work, but it will start to fail if there are multiple super types:

@ContributesBinding(MyScope::class)
class RealFoo : Foo<Bar, Baz>, SecondSuperType

In this case you have to use the boundType parameter, but with that you cannot specify the type parameters:

@ContributesBinding(MyScope::class, boundType = Foo::class)
class RealFoo : Foo<Bar, Baz>, SecondSuperType
