Provide smarter default query string key names for views exposed filters

Describe your issue or idea

I almost always override the keys views uses for it's query strings, here:

By default, it uses the machine name of each field, but those machine names can be cumbersome, and are sometimes very long. I always remove field_ from the name of the key, and sometimes change the key entirely to match the field label instead.

As was raised in https://github.com/backdrop/backdrop-issues/issues/2843, we might want to do this automatically for our users, which would also do a better job of keeping cleaner, shorter query strings for embedding as links into other posts.
