Adding the builders to the LayoutKitObjC pod.
This required moving the objc enums to the header files, since objc builders cannot depend on Swift implementation.
Since the cross-language integration depends on header files that match the module name, creating a new LayoutKitObjC target for Xcode build to use to match the cocoa pods build.
Verified that build succeeds for Xcode and pod lib lint.
