I think these comments are slightly out-of-date, and we'll still want to static
assert that they match the blink counterparts (also I think you're missing the
gyp/gn additions for the Java enum generation?).

- Updated the comments.
- Removed the CPP-Java-enum directives completely. Will add them plus the build
rules in the other (follow-up, platform-specific) CL.
- Fixed enum naming style as per mkosiba's comment in the other CL.
