This PR merges those two sets, into a new package `jdk.javadoc.internal.html` that is now used by both `doclint` and the standard doclet.

But, one small item of note: `enum HtmlStyle` was split into `interface HtmlStyle` and `enum HtmlStyles implements HtmlStyle` to avoid having a doclet-specific enum class in the new `internal.html` package.  The naming follows `HtmlId` and `HtmlIds`.
