color: move hgext.color._styles to mercurial.color.style
This is small first step to start moving the color infrastructure into core. The
current code of the color extensions is full of strange and debatable things,
we'll clean it up in the process as having things into core help the cleaning.
Moving _style was the simplest sensible move that is possible. It will also help
cleaning up the extension setup process in a later changesets.
