GHC 9.12

Update for GHC 9.12.1

[alanz]

This is a work in progress.
It needs cleaning up, I spread CPP everywhere, and broke the non-9.12.1 versions

And if I run

cabal test --test-option="-p /Fixity.hs/"

It fails with

    Expected type not found at the location specified in the refact file.
      Expected type: HsExpr (GhcPass 'Parsed)
      Location: tests/examples/Fixity.hs:1:21-27: inappropriate type

And that span is not in the new AST. So I am not sure if the refact test file needs updating

[alanz]

I am down to 3 failures, all of which are perhaps "external"

    Use -p '/tests\/examples\/Structure7.hs/' to rerun this test only.

Caused by a spacing change in ghc-exactprint where there is now a new LHS counter initialisation to 0 not 1, to match nested logic, but gives off by one at the top level.

The next two are related to the refact hint input not matching the span, because the AST shows up differently. I am not sure how to deal with them

    Use -p '/tests\/examples\/Lambda37.hs/' to rerun this test only.
    Use -p '/tests\/examples\/EtaReduceLocalTypeSig.hs/' to rerun this test only.
