Named form getter
This PR contains changes related to adding named getter in Servo for getting the list of all meaningful property names for a HTMLFormElement object, and getting the value of a specific property name. The following changes have been made:
* uncomment the [named getter](f63b404e0c/components/script/dom/webidls/HTMLFormElement.webidl (L30)) from HTMLFormElement.webidl
* add the missing `NamedGetter` and `SupportedPropertyNames` methods to [HTMLFormElement](f63b404e0c/components/script/dom/htmlformelement.rs (L113))
* implement `SupportedPropertyNames` according to [the specification](https://html.spec.whatwg.org/multipage/forms.html#the-form-element:supported-property-names):
* create an enum to represent the `id`, `name`, and `past` states for the sourced names
* create a vector of `(SourcedName, DomRoot<HTMLElement>)` by iterating over `self.controls` and checking the element type and calling methods like `HTMLElement::is_listed_element`

Various webxr WPT fixes

r? @asajeffrey
Went through most of the failing tests and fixed them. Many of the remaining ones fail due to unsupported features that I can slowly whittle away.
implement composition event creation in Document.createEvent
Solved the problem mentioned in https://github.com/servo/servo/issues/24724#issuecomment-562326328
Add logic to create composition event for Document.createEvent. This resolved some WPT test failure, so updated the metadata as well

Took out the special mouseover cancel case
<!-- Please describe your changes on the following line: -->
eventtarget.rs was checking the event type to see if it was a mouseover; now it doesn't. Other special-case events like error and beforeunload go down other code paths entirely, so this one has no special cases left.

Remove unnecessary thread in filereader, add stream TODO
<!-- Please describe your changes on the following line: -->
I think there are no benefits to queuing the various `FileReadingTask` from a thread, and reading the actual blob bytes are still done on the main-thread. We could try to move the reading off the main-thread(but note the `Blob` is not something you would want to move to another thread "as-is" since it's a `DomObject`), and I think we should just aim for implementing streams and follow the spec instead.

hidden field named _charset_ now appears in FormData as UTF-8
<!-- Please describe your changes on the following line: -->
HTMLInputElement now has special case logic for putting a hidden field named `_charset_` in an entry set. To support this, the encoding used when constructing a form dataset is now being passed further down the callchain than it was before.
