[Feature request] Ignore lines in HBS with {{! glint-ignore }} or something

Ability to ignore lines in HBS would be great.

We've punted on this so far because figuring out the right mapping is a bit thorny. Since // @ts-ignore operates on a line-by-line basis, and HBS lines don't necessarily map 1:1 to the emitted TS, we need to be a little bit thoughtful about what we emit in this scenario to avoid either making it impossible to ignore certain things or accidentally squashing too much instead.

That's not to say having a @ts-ignore (and/or maybe preferably @ts-expect-error) equivalent isn't valuable, though—it's definitely on the radar!
