… ID (swiftlang#1799) ## Combine a parameterized test case's argument IDs into a single hashed ID ### Motivation: `Test.Case.ID.argumentIDs` previously stored one `Argument.ID` per argument, in order. This meant the ID grew with the number of parameters. I want to simplify this to a single combined ID that identifies the whole combination of arguments. rdar://182725918 ### Checklist: - [x] Code and documentation should follow the style of the [Style Guide](https://github.com/apple/swift-testing/blob/main/Documentation/StyleGuide.md). - [x] If public symbols are renamed or modified, DocC references should be updated. --------- Co-authored-by: Suzy Silver <suzysilver@apple.com>
