Re: [csswg-drafts] [cssom-view] Add notIfViewed to ScrollIntoViewOptions; add FocusScrollOptions

Another approach could be to add "-if-needed" suffixes to the keywords in LogicalScrollPosition. The current `nearest` already has "if needed" semantics, as specified. This would give more control as it lets developers specify "if needed" separately for the two dimensions.

focus({ preventScroll: true });
focus({ scrollOptions: { block: "center", inline: "center" } });
focus({ scrollOptions: { block: "center-if-needed", inline: "center-if-needed" } });
scrollIntoView({ block: "start" });
scrollIntoView({ block: "start-if-needed" });
enum ScrollLogicalPosition { "start", "start-if-needed", "center", "center-if-needed", "end", "end-if-needed", "nearest" };
(No change to `nearest` for compat.)
