 Drop old integer-gmp-0.5 from GHC source tree

 This completes what c774b28f76ee4c220f7c1c9fd81585e0e3af0e8a (#9281)
 started.  `integer-gmp-1.0` was added as an additional
 `libraries/integer-gmp2` folder while retaining the ability to configure
 GHC w/ the old `integer-gmp-0.5` to have a way back, and or the ability
 to easily switch between old/new `integer-gmp` for benchmark/debugging
 purposes.

 This commit removes the old `libraries/integer-gmp` folder and moves
 `libraries/integer-gmp2` into its place, while removing any mentions of
 "gmp2" as well as the to support two different `integer-gmp` packages in
 GHC's source-tree.
