[FUSE] Folding range whitespace differences at the end of blocks

[davidwengier]

Not sure if this is a tooling issue, or difference in results from Roslyn caused by a runtime/designtime compilation difference.

Example differences:

I think this is a bad user experience as, in the example above, the closing div tag would end up displayed on the same line as the @if when collapsed.

#10959 marks an integration test as skipped referencing this issue. Please unskip when fixing :)

@jaredpar Yep, I mentioned this one previously. We've been fixing these on an ad-hoc basis but it turns out it's an issue with any @ directive that razor parses directly.

I plan to fix that holistically rather than doing more one at a time patches, but we're getting into the long tail of what users actually see so not considering this a blocker for fuse rollout right now.

(Aside, apologies I guess I didn't put these issues into milestones but have already triaged them).
