Update cabal-helper to version 0.8.1.2 that supports Cabal (>=1.14 && <1.26 || >=2.0 && <2.5)

Building cabal-helper-0.8.1.2 with Stack failed with 'Dependency cycle detected' error. It seems to be https://github.com/commercialhaskell/stack/issues/4265 Stack bug. As a temporary solution I added source code of cabal-helper package to vendor directory and commented out 'build-tool-depends:  cabal-helper:cabal-helper-wrapper' line in the cabal-helper.cabal file.

+Module      : CabalHelper.Shared.InterfaceTypes
+Description : Types which are used by c-h library and executable to communicate
+License     : GPL-3
+
+These types are used to communicate between the cabal-helper library and main
+executable, using Show/Read. If any types in this module change the major
+version must be bumped since this will be exposed in the @Distribution.Helper@
+module.
+
+The cached executables in @$XDG_CACHE_HOME/cabal-helper@ use the cabal-helper
+version (among other things) as a cache key so we don't need to worry about
+talking to an old executable.
