changelog: [transmutes_expressible_as_ptr_casts]: Fix suggestion missing wrapping parentheses

Fixes #10449

r? @Jarcho

Is this the best way to go about this? unused_parens will catch the unnecessary ones but emitting them in the first place isn't ideal

You can check if the parent expression's precedence is >=PREC_PREFIX. I don't think as casting has a constant.
