Fixes #12785
Unfortunately the changes here are pretty big, and especially sadly one part we have to specifically check for block bodied lambdas. The upside is that this change also improves formatting for one other case, that is multiline expressions in attributes. Added a bunch of new tests that hopefully cover all of the weird possibilities here. Lambdas continue to be a painful part of formatting, but at least now we're only dealing with the ones the user writes, and not the ones the Razor compiler uses everywhere, which at least means failure modes should be more forgiving.
