 Remove `setUnfoldingInfoLazily`

 The definition of `setUnfoldingInfoLazily` is exactly the same as
 `setUnfoldingInfo` and is only used in one place, `TcIface`.

 They were made equivalent in 2010 in
 2ff2497dc374175b8ed81446258baf208d1f3e6e with the commit message.

 Original File:  compiler/basicTypes/IdInfo.lhs

 Don't seq unfoldings
 We generate intermediate unfoldings which are just thrown away, so
 evaluating them is a waste of time.

 Closes #12453
