Give more guarntees about ImplicitParams (#23289)

- Added new section in the GHC user's guide that legends behavior of
nested implicit parameter bindings in these two cases:

  let ?f = 1 in let ?f = 2 in ?f

and

  data T where MkT :: (?f :: Int) => T

  f :: T -> T -> Int
  f MkT MkT = ?f

- Added new test case to examine this behavior.
