Cannot use array/list/etc literals in attribute parameters

The following code fails to compile:

```fsharp
open System
open Xunit

[]
[]
let banana (x, y, maybe, arr) = ()
```

This is because array literals are not considered constants for the purposes of attribute checking: https://github.com/dotnet/fsharp/blob/9be86c23a9540c41929ff3dbcd904d069ba34a34/src/fsharp/PostInferenceChecks.fs#L1589-L1613

Although not idiomatic F#, this pattern exists in multiple test frameworks (NUnit has the same feature) and should probably typecheck, considering it is allowed in C#.
