Move the `Text.Read` implementation into `base`
This contribution moves the implementation of Text.Read into base, thus getting rid of GHC.Internal.Text.Read and opening up more code to be moved out of ghc-internal.
Due to a large amount of spam we do not allow new users to create repositories, they are "external" users. If you are a new user and want to create a repository, for example for forking GHC, open a new issue on ghc/ghc using the "get-verified" issue template
