We can reset `<input type=text>` fields! I wish I could've done something with checkboxes, but unfortunately, that's it for now.
In addition to that, this PR implements `HTMLInputAttribute.defaultValue`, updates wpt-test to expect passing tests as a result of that implementation, and fixes an index error crash with text inputs.
edit: also includes an html example where one may lazily watch form resets in action: ` tests/html/form_reset_handsfree.html`

Fixes#3918
Can be tested in `tests/html/textarea.html`. Also implemented some content reflecting IDL attributes for HTMLTextAreaElement while I was in there.
There are some major problems with TextInput when Multiple is enabled that I haven't addressed here, but I'm prepared to open up a follow-up issue.

This is missing a lot of parts, so it doesn't really make any real-world form submission work yet. It provides a skeleton on which the missing bits can be filled in.
What works:
- `<input>` elements except for `type=file`
- GET/POST methods
- URLencoded `enctype`s (default)
- Submission via `<form>.submit()` only
Stuff that needs to be done for most simple real-world cases to work:
- [Working text input](https://github.com/servo/servo/pull/3585)
- Click handlers for `<submit>`
- Possibly `<textarea>` support
- Support for the other two enctypes (#3649)
Todo:
- Correctly implement [planned navigation](https://html.spec.whatwg.org/multipage/forms.html#planned-navigation) using `TrustedFormAddress` (#3648)
- [Correctly implement form owners.](https://github.com/servo/servo/issues/3553) Requires html5ever and some discussion of the spec.
- `<input type=file>` support
- Image submit support
- Browsing contexts/targets
- Support for non-`<input>` controls
- Validation (?)
- Dirname (?)
