Subject: [PATCH] style: Use separate Scrollbar and ThemedScrollbar ColorIDs.

Otherwise on Windows, we have a ColorID::Scrollbar but not any of the other scrollbar part
colors, and the Windows-provided value for Scrollbar doesn't work well
with the default values for the other scrollbar parts that come from the
non-native theme.
