Route Xcode version information through an implicit dependency instead of the configuration.

This is part of the crusade to kill package loading in configuration creation.

AppleConfiguration still retains the version information for the following reasons:
- Some Skylark rules access it that way. The plan is to create an xcode_config_alias() rule that can be an implicit dependency of Skylark rules and to export the version information to Skylark from XcodeVersionsProvider.
- The minimum OS version is part of the name of the output directory. The plan for that is simply to remove it. Hopefully we can get away with it.
- They allow us to add assertions to make sure the new mechanism works like the old one.

RELNOTES: None.
