Plan for GHC 9.2

[Adam Gundry]

[Re-sending from the correct address, apologies!]

It would be great to get RecordDotSyntax for selection into 9.2.

As I just commented on !4532 [1] there's one awkward point to resolve,
which is that 9.2 will probably not have `setField`, on which
RecordDotSyntax updates depend.

Cheers,

Adam
