Merge pull request #14123 from cwakamo/fix-build-script-playground-frameworks

- Remove support for building PlaygroundLogger on Linux (this never actually worked, so it doesn't make sense to keep maintaining something which doesn't work).
- Merge the "playgroundsupport" and "playgroundlogger" products in build-script and update presets where necessary
- Update how PlaygroundLogger and PlaygroundSupport are built, taking advantage of a new workspace and new schemes to do per-platform xcodebuild invocations (requires changes in swift-xcode-playground-support).
