Does this not generate anything that we can refer to from CSSResourceValue.h?

It doesn't seem to - for example the enum LengthType in
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/css/cssom...
just results in an array of valid values in the generated V8CSSLengthValue:
https://cs.chromium.org/chromium/src/out/Debug/gen/blink/bindings/core/v8/V8C....
I couldn't find any other references to "LengthType" in the generated code.
