Document ext/uri

Another attempt to document ext/uri after #5060

Some of my sentences are very clunky, so I am happy to receive suggestions.

First pass at comments. Didn't yet look at all files, but this looks like a good start. Will take another look after you reviewed my comments to avoid looking at all files twice in case they change.

Here it might make sense to also link to Uri\WhatWg\Url::withUsername (second position).

Suggested change

	<member><methodname>Uri\WhatWg\Url::getPassword</methodname></member>
	<member><methodname>Uri\WhatWg\Url::getPassword</methodname></member>
	<member><methodname>Uri\WhatWg\Url::withUsername</methodname></member>

I think doing so would make more sense for Uri because password is just a pseudo component together with username. For WHATWG URL, they are completely separate components with not much more connection than e.g. the host and port. I'm not against adding it though, so if you have a strong opinion, then I'm fine with it.

I feel username and password logically belong together (e.g. because setting a password will also add an empty username) and thus I would cross-link them.

I've just aded the documentation for the two ext/uri enums. Could you please have another look sometime soon? :)

[TimWolla]

Okay, gone through all files now. Skimmed some of them. If this is resolved, the PR should be good enough for merging and I'll then double-check the rendered version and send PRs 😄

Should this link to the userinfo methods?
