This reverts commit 59c5fe1d4b624423b1c37891710f2757bb58d6af.
This commit added two duplicate jobs on all validate pipelines, so we
are reverting for now whilst we work out what the best way forward is.

This change makes PythonCmd resolve to a canonical absolute path on
Windows, which prevents HLS getting confused (now that we have a
build-time dependency on python).

This patch finally (I hope) nails the question of whether
(forall a. ty) and (forall a -> ty)
are `eqType`: they aren't!
There is a long discussion in #22762, plus useful Notes:
* Note [ForAllTy and type equality] in GHC.Core.TyCo.Compare
* Note [Comparing visiblities] in GHC.Core.TyCo.Compare
* Note [ForAllCo] in GHC.Core.TyCo.Rep
It also establishes a helpful new invariant for ForAllCo,
and ForAllTy, when the bound variable is a CoVar:in that
case the visibility must be coreTyLamForAllTyFlag.
All this is well documented in revised Notes.
