About two years have passed, and I haven’t seen any progress on site isolation on non-Cocoa platforms. Is there anyone planning to implement such support?

Basically all the use of LayerHostingContextIdentifier in that directory needs an equivalent implementation for other graphics implementations, like in the CoordinatedGraphics directories. There is one layout test in LayoutTests/http/tests/site-isolation/basic-iframe.html that is currently skipped on all non-Cocoa platforms.
