This pr changes the collator interface function to return an optional collation instead of a collation. This is required as the parachain itself can fail to generate a valid collation for various reason. Now if the collation fails it will return `None`. Besides that the pr adds some `RuntimeDebug` derive for `ValidationData` and removes some whitespaces.

There was a problem hiding this comment.
This is as we discussed in Element. I do not object to using Option here instead of Result.
