The new formatter supports opting a region of code out from being formatted. I'm applying this marker to all of the multitests since those tests are often very sensitive to formatting and easily broken. This way, anyone touching a multitest (including me when I reformat the tests) doesn't have to remember to not run the formatter on it. Unfortunately, this doesn't opt out 100# of the multitests. There are a handful of multitests that also contain "@dart=" comments and are thus formatted using the old style where the "// dart format off" marker has no effect. For those, we'll have to still be careful to not accidentally format them.
