For deriving newtype and deriving via, in order to bring type variables
needed for the coercions into scope, GHC generates type signatures for
derived class methods. As a simplification, drop the type signatures and
instead use type abstractions to bring method type variables into scope.

driverPlugins are only run when the plugin state changes. This meant they were
never run for static plugins, as their state never changes.
We need to keep track of whether a static plugin has been initialised to ensure
we run static driver plugins at least once. This necessitates an additional field
in the `StaticPlugin` constructor as this state has to be bundled with the plugin
itself, as static plugins have no name/identifier we can use to otherwise reference
them

ci.sh sets up the toolchain environment, including paths for the cabal directory, the
toolchain binaries etc. If we run any commands outside of ci.sh, unless we
source ci.sh we will use the wrong values for these environment variables.
In particular, I ran into an issue where the cabal invocation `hadrian/ghci` was
using an old index state despite `ci.sh setup` updating and setting the correct
index state. This is because `ci.sh` sets the `CABAL_DIR` to a different place, which
is where the index was downloaded to, but we were using the default cabal directory
outside ci.sh
The solution is to source the correct environment `ci.sh` using `. ci.sh setup`

A side-effect of this patch is that we now allow negative unsigned

Improves the design of FieldOcc vs AmbiguousFieldOcc, and removes a
dependency on `RdrName` from the Language.Haskell.* namespace (#21592).
The design:
* The FieldOcc constructor of FieldOcc always refers to an unambiguous
field occurrence.
* During renaming, a FieldOcc may be ambiguous and only be resolvable
during Typechecking
* Therefore, we extend (with TTG) `FieldOcc GhcRn` with a constructor
`AmbiguousFieldOcc` that constructs a definitely ambiguous `FieldOcc`.
* During typechecking, all ambiguous field occurrences must be resolved,
so the `AmbiguousFieldOcc` constructor no longer exists

There are two issues:
- FieldOcc used to only have one constructor and always be unambigious, this is no longer the case. Calls to foLabel are thus partial now. Don't know how much we care about this, since the partial calls are mostly inside functions that used to operate on the operate on the unambigious FieldOcc
- Lots of functions that take in a FieldOcc, or a HsExpr (with the HsRecSel constructor) now have a new case. It was not always clear to me what the correct implementation was for these. I have filled them in as far as I could and left one undefined...
