Add Skylark code that exports the current Xcode version and the Apple SDK versions as flags.
This will serve to replace AppleConfiguration#lateBoundOptionDefaults(). That one has to go away so that AppleConfiguration doesn't need to know the contents of the xcode_config rule anymore.
Progress towards #3424.
RELNOTES: None.
