Auto merge of #10606 - servo:remove-url-plugin, r=nox

Remove the url! plugin.

In rust-url 1.0 the `Url` struct is going to have private fields, and there is no way to to create an aribitrary one without going through the parser.

The plugin never had a clear demonstrated performance benefit, it was made mostly because it was possible and relatively easy at the time.

This commit was originally part of #9840, but it’s taking a while to land and I keep removing new uses of `url!` when rebasing.

r? @nox
