I added a dimension to the test matrix, but Mergify is waiting for the old one. Strange.

@michaelpj After some rewrites, I'm finally happy with the current version. The most notable change is that now we always store a UTF-8 encoded `ShortByteString` in `NormalizedFilePath`, so that `toNormalizedFilePath...

Converting between `OsPath` and `FilePath` requires the ability to express failure. So we can not preserve the signature of functions like this, if `NormalizedFilePath` contains `OsPath` but not `FilePath`. ```...

But keep in mind that using the new `filepath` requires projects that depends on `ghc` [to upgrade to GHC 9.6](https://github.com/haskell/haskell-language-server/issues/3046), which is not possible for HLS in the near future....
