Clean up haddock hyperlinks of GHC.* (part2)

This updates haddock comments only.

This patch focuses to update for hyperlinks in GHC API's haddock comments,
because broken links especially discourage newcomers.

This includes the following hierarchies:

  - GHC.Iface.*
  - GHC.Llvm.*

  - GHC.Rename.*
  - GHC.Tc.*

  - GHC.HsToCore.*
  - GHC.StgToCmm.*
  - GHC.CmmToAsm.*

  - GHC.Runtime.*

  - GHC.Unit.*
  - GHC.Utils.*
  - GHC.SysTools.*
