fix(53204): Bug: __runInitializers(this) is emitted before super() call

Fixes #53204

[DanielRosenwasser]

Should we do one last cherry-pick/LKG if we can get the fix in today?

[jakebailey]

This pattern of findSuperStatementIndex is already used by both the ts transform (see transformConstructorBody) and the classFields transform (see transformConstructorBody); it seems like it'd be best to be able to fix these in such a way that we don't have to fix this bug over and over again, but, I'm not sure what that looks like.

So, LGTM, but I don't think my +1 should be the determining factor in if this fix is final or backportable.

[DanielRosenwasser]

Given that we have an error if super() doesn't appear at the top level, I think we can bring this in.
