This is preparation for sharing this code with layout_2020 and
implementing selective off-the-main-thread animations.
We still look for nodes not in the flow tree in the layout thread.
Added WebIDL bindings for `GPUCommandEncoder`, `GPUCommandBuffer`, `GPUComputePassEncoder`, `GPUProgrammablePassEncoder`.
Implemented the `beginComputePass`, `copyBufferToBuffer` and `finish` functions of `GPUCommandEncoder`.
Implemented the `createCommandEncoder` function of `GPUDevice`.
Added WebIDL bindings for `GPUBindGroupLayout`, `GPUBindGroupLayoutDescriptor`, `GPUBindingType`, `GPUShaderStage`
and `GPUBindGroupLayoutBinding` (Note: The servo's codegen doesn't like the name, because its already occupied).
Implemented the `createBindGroupLayout` function of `GPUDevice`.
Only start WebGPU thread if an adapter is requested

This addresses 1 and 2 from https://github.com/servo/servo/issues/24706#issuecomment-555491438
We send a message to constellation instead of creating the `WebGPU` thread on the start. We send back the result to script and set the `Window`'s `web_gpu` component there.

Added WebIDL bindings for GPUBuffer, GPUBufferDescriptor, GPUBufferUsage
Implemented the `createBuffer` and `createBufferMapped` functions of GPUDevice
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`
