Experimental collection literal construction bug

Enabling: https://kotlinlang.org/docs/whatsnew-eap.html#support-for-collection-literals

https://youtrack.jetbrains.com/issue/KT-43871/Collection-literals

```kt
val df = dataFrameOf(
"fruits" to ["apple", "banana", "cherry"],
"veggies" to ["carrot", "broccoli", "spinach"],
"animals" to ["dog", "cat", "bird"],
)
```
```
e: tmp.kt:7:14 Overload resolution ambiguity between candidates:
fun dataFrameOf(vararg columns: Pair>): DataFrame
fun dataFrameOf(vararg columns: Pair>): DataFrame
```

This works:
```kt
val df = dataFrameOf(
"fruits" to ["apple", "banana", "cherry"],
"veggies" to ["carrot", "broccoli", "spinach"],
"animals" to listOf("dog", "cat", "bird"),
)
```

Start by reproducing the ambiguity with the collection-literal example and inspect the dataFrameOf overloads shown in the error. Compare this with the working listOf example; done means collection literals select an unambiguous dataFrameOf overload while preserving the existing listOf behavior.
