Non-idiomatic 'is' type check for an object

Reports non-idiomatic is type checks for an object.

It's recommended to replace such checks with reference comparison.

Example:

object Foo fun foo(arg: Any) = when { arg is Foo -> ... arg !is Foo -> ... }

After the quick-fix is applied:

object Foo fun foo(arg: Any) = when { arg === Foo -> ... arg !== Foo -> ... }
