As part of the collections reform RFC, this commit removes all collections traits in favor of inherent methods on collections themselves. All methods should continue to be available on all collections. This is a breaking change with all of the collections traits being removed and no longer being in the prelude. In order to update old code you should move the trait implementations to inherent implementations directly on the type itself. Note that some traits had default methods which will also need to be implemented to maintain backwards compatibility. [breaking-change] cc #18424
