CSF: Make sure loaders/decorators can be used as array

[kasperpeulen]

What I did

Make sure loaders/decorators can be used as array.

Our type definitions allow both an array as a function to be assigned to loaders or decorators. This worked in 7.6 but regressed in 8.0.

Can you provide some background on this fix? There isn't an issue linked, and I don't understand the motivation.

@valentinpalkovic Our type definitions allow both an array as a function to be assigned to loaders or decorators. This worked in 7.6 but regressed in 8.0. So I fixed it and added a unit test :)
