Suggest a comma if a struct initializer field fails to parse

Currently, we emit a "try adding a comma" suggestion if a comma is
missing in a struct definition. However, we emit no such suggestion if a
comma is missing in a struct initializer.

This commit adds a "try adding a comma" suggestion when we don't find a
comma during the parsing of a struct initializer field.

The change to `src/test/ui/parser/removed-syntax-with-1.stderr` isn't
great, but I don't see a good way of avoiding it.
