Support swiftly fixing quick fix errors one after another

[Tyriar]

Testing #194072

Repro:

1. Create 2 errors on a line
2. cmd+.
3. enter
4. wait a second
5. cmd+.
6. enter

Doing this slowly works fine:

Doing it quickly fails:

I've had some folks mention this before as well (not just in the context of this feature) - It's an issue with how the diagnostics are formed. (like how sometimes you hit ctrl + . for the quickfix menu before the error shows up in anticipation of the quickfix being there)

Will do some exploration on how we can optimize this (may be resolved with how I'm handling multiple quickfixes, mentioned in your issue here #194222)

@justschen the error underline never went away though, so could we be optimistic about this and assume it's still valid if the range for that problem didn't change?

You're right, that's interesting. I'll give it a look 🤔

@mjbvz I think this might have something to do with the LSP side of things? I've seen some related issues about errors not being picked up fast enough and people hitting ctrl + . anticipating an error, but the diagnostics have not shown up yet.

Yes seems like a duplicate of #117812. Right now we have to manage passing diagnostics to TS Server and these easily get out sync the server
