Remove obsolete HasInstance behavior per heycam/webidl #356
This turns one WPT test from fail to pass and it leaves Servo with a little less platform object special-case code to worry about.

Autocomputed content-type header now reaches net request
The spec expects that for a DOM Request r, r.headers and r.request can actually refer to the same header list in RAM, with changes to one affecting the other. This is mostly unobservable, but it happens to come up at the point in the Request constructor that auto-infers a content type from the body, so now after inferring the content type it injects it into both header lists instead of one.
Remaining test failures are due to the way Hyper crates normalize semicolons in MIME types, and an actually separate problem about content-lengths that I haven't sniffed out yet.

Implement MessageEvent.InitMessageEvent

InitMessageEvent had to be implemented as required by wpt. For this few keys of struct `MessageEvent` are now wrapped inside DomRefCell wrapper.

Use Windows 10 instead of 7 in user agent string
<!-- Please describe your changes on the following line: -->
I tried testing https://my.panomoments.com/ in the latest nightly version of Servo but it wouldn't load because it requires Windows 8 or newer and Servo's user agent string says it's using Windows 7. This change should allow sites requiring a modern version of Windows to run. This could potentially cause issues for users running older versions of Windows however. A better long term solution would be to do #18194.

Let hyper automatically set the host header if needed
Google's gws web server did not expect to receive an unneeded Host header via HTTP/2, therefore it responded with 400 Bad Request over a working HTTP/2 connection.
https://tools.ietf.org/html/rfc7540#page-55
> Clients that generate HTTP/2 requests directly SHOULD use the ":authority" pseudo-header field instead of the Host header field.
It's hyper's job to take care of this for the HTTP/1 case, therefore we can remove old code.
When calling [Client::builder()](1974c875a1/components/net/connector.rs (L116-L119)) we do not disable hyper's default [set_host](4b6099c7aa/src/client/mod.rs (L1019-L1024)) config option, therefore hyper [automatically adds a Host header for non-HTTP/2 connections](4b6099c7aa/src/client/mod.rs (L289-L292)) based on the [URI](3f663d7ab2/components/net/http_loader.rs (L418-L421)).

Some information of `canvas_data::Pattern` was lost by
converting it to `raqote::Source` due to the fact that Raqote
did not store this information (e.g. linear gradient's start/end
points). We introduce another layer to keep this information for later
use (like in `is_zero_size_gradient()`).
From `addColorStop(offset, color)`s spec:
If multiple stops are added at the same offset on a gradient, they must
be placed in the order added, with the first one closest to the start of
the gradient, and each subsequent one infinitesimally further along
towards the end point (in effect causing all but the first and last stop
added at each point to be ignored)

Added WebIDL bindings for GPUBuffer, GPUBufferDescriptor, GPUBufferUsage
Implemented the `createBuffer` and `createBufferMapped` functions of GPUDevice
Removed createEvent cases, removed now-unused new_uninitializeds
<!-- Please describe your changes on the following line: -->
document.createEvent was creating some event types WHATWG now says shouldn't be created that way. This was the only caller of a few new_uninitialized methods, so those are removed too.

De-deplicate is_cors_safelisted_request_header helper functions
<!-- Please describe your changes on the following line: -->
Separate is_cors_safelisted_request_header implementations in script::dom::request and net::fetch::methods have been merged to a single implementation in net_traits::request, with additional logic for spec requirements that weren't previously there. This doesn't pass all the failing tests, but it doesn't fail any passing ones either and it reduces confusion about what's supposed to happen where.

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`
