Multiline inner "record" not properly highlighted

[fbricon]

2nd part of #1442: Inner Java 14's record, when the record keyword is on a separate line, is not properly colored, even with semantic highlighting turned on.

public class Demo {
  public static void main(String[] args) {
    record
    Foo(int i,int j){}
    Foo foo = new Foo(0, 1);
    System.out.println(foo);
  }
}

is displayed as:

@Eskibear is this something you can help with?

I find that the issue also exists for multi-line inner class.

public class Foo {
    public static void main(String[] args) {
        class 
        Bar {
            
        }
    }
}

In the main function you'll see both class and Bar are not highlighted. Turn semantic highlighting on, it will highlight Bar (types and variables have been supported), but the class is still not highlighted (semantic highlighting for keywords hasn't been implemented).

Semantic highlighting should be the right way to go, but some investigation is required as I don't know how far RecordDeclaration has been supported in upstream JDT core.

As for keywords like "class" and "record", it would be good and cheap to leverage syntax highlighting (as long as they got atom/language-java#186 fixed).
