Components features missing from Locale

[MCJack123]

Description

The Locale.Components struct (introduced in iOS 16/macOS 13), and its associated methods and constructors in Locale, are not implemented in this version of Foundation. This makes it impossible to use locales with different components on non-Apple targets.

Expected behavior

The Locale struct is up-to-date with the current macOS/iOS Foundation library, including Locale.Components.

Actual behavior

Locale.Components is missing, preventing compilation of code that uses it.

Environment

• Arch Linux (latest)
• Swift 5.9.2 (Red Hat UBI9)
• Whichever swift-corelibs-foundation ships with Swift 5.9.2
