Fix CSSOM.patch for compatibility with Embedded Swift

The CSSOM module has different context after previously applied changes for Embedded Swift support. `override` modifiers are not applicable with embedded Swift and need to be replaced with `final`. Similarly `Self` is replaced with explicit class names to avoid use of implicit metatypes currently incompatible with Embedded Swift. Certain initializers also had to become `public` to be usable in library clients.
