Issue #23614: GHCi spelling suggestions during :info

Responding to #23614

Suppose there is a variable misspelled == 100 in scope. Previously, :t misspelld would suggest the corrected spelling, but :i misspelld would not in GHCi. This MR attempts to add this feature to the :i command.

The key part of this patch is to make both compiler/GHC/Rename/Env.hs and compiler/GHC/Tc/Module.hs depend on code in compiler/GHC/Rename/Unbound.hs for the purpose of finding misspelled names. This is through the similarNameSuggestionsM function that latter module now exports.
