Rollup merge of #133151 - tyrone-wu:trim-fn-ptr-whitespace, r=compiler-errors

Trim extra whitespace in fn ptr suggestion span

Trim extra whitespace when suggesting removal of invalid qualifiers when parsing function pointer type.

Fixes: #133083

I made a comment about the format of the diagnostic error message in rust-lang/rust#133083 (comment). I think the `.label` may be a little redundant if the diagnostic only highlights the bad qualifier instead of the entire `TyKind::BareFn` span. If it makes sense, I can include it in this PR.
