<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Check for duplicate variables in associated default equations

A follow-up to !696's, which attempted to clean up the error messages

for ill formed associated type family default equations. The previous

attempt, !696, forgot to account for the possibility of duplicate

kind variable arguments, as in the following example:

```hs

class C (a :: j) where

  type T (a :: j) (b :: k)

  type T (a :: k) (b :: k) = k

```

This patch addresses this shortcoming by adding an additional check

for this. Fixes #13971 (hopefully for good this time).

This addresses some glaring omissions from

`libraries/base/changelog.md` and

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16632 by using the correct SrcSpan in checkTyClHdr

`checkTyClHdr`'s case for `HsTyVar` was grabbing the wrong `SrcSpan`,

which lead to error messages pointing to the wrong location. Easily

fixed.
