We use Size2D and Point2D across compositing, constellation and script,
losing the type of pixels we use (DevicePixel, DeviceIndepententPixel
or CSSPixel) along the way, which might lead to bugs like
window.outerHeight not taking into account the page zoom (using
DeviceIndepententPixel instead of CSSPixel).
Update the MULTIPROCESS static when changing default options
<!-- Please describe your changes on the following line: -->
When the options are set not from the command line but by calling `set_defaults()` which is common for embedders, the MULTIPROCESS static is not set, and so the setting is ignored. This patch fixes that.

refactor(window): reference winit where applicable
<!-- Please describe your changes on the following line: -->
This is nearly first changes to rustlang code and I suspect I could make possible mistakes lot, please point me anything if need to be updated. 🙏
This PR intends to update codebase per #20299 , mostly followed suggestion around https://github.com/servo/servo/issues/20299#issuecomment-373171416 to update reference to use `winit` where applicable. Confirmed local build / check works correctly for updated references.

Support JS typed arrays as arguments and in WebIDL unions
<!-- Please describe your changes on the following line: -->
Supersedes #20205.
This brings support to receiving typed arrays as function arguments (those are stack-rooted with CustomAutoRooter) and also being a member of a union (which is basically heap-rooted? similarly to other webidl unions).
This is based on my other PR #20265 (which means it has to pull an external rust-mozjs branch and contains some also slightly unrelated changes here) since it shares `RootedTraceableBox::from_box` here and some other additional changes at rust-mozjs, but it can be easily separated if needed.
I tried adding support to nullable typed arrays but couldn't work around an issue of codegen always sticking a "OrNull" at the end of my type (presumably because of [this](https://github.com/servo/servo/blob/master/components/script/dom/bindings/codegen/parser/WebIDL.py#L2241)?). How would I go about avoiding the suffix with nullable arguments?
If we were to add also support for nullable typed arrays then I think we wouldn't be blocked anymore on this in WebGL 1.0.

Fix JS object conversion in unions
<!-- Please describe your changes on the following line: -->
Requires safe `Heap::boxed` constructor from https://github.com/servo/rust-mozjs/pull/395 (more info on it is in the PR).
Since unions currently assume that their respective members root themselves and can be stored on heap, I modified the union member object conversion branch to convert to a `RootedTraceableBox<Heap<*mut JSObject>>` (which is the currently generated type for objects in said unions).
I did it only for Unions and not dictionaries, since some dictionaries had bare `*mut JSObject` members - is this a mistake and something that needs further fixing?
Does this need a test, e.g. passing a union with object to a function that returns said object, and comparing the results for equality?
r? @jdm
Generated code with this patch (for `StringOrObject`):
```rust
impl FromJSValConvertible for StringOrObject {
type Config = ();
unsafe fn from_jsval(cx: *mut JSContext,
value: HandleValue,
_option: ())
-> Result<ConversionResult<StringOrObject>, ()> {
if value.get().is_object() {
match StringOrObject::TryConvertToObject(cx, value) {
Err(_) => return Err(()),
Ok(Some(value)) => return Ok(ConversionResult::Success(StringOrObject::Object(value))),
Ok(None) => (),
}
}
// (...)
}
}
impl StringOrObject {
// (...)
unsafe fn TryConvertToObject(cx: *mut JSContext, value: HandleValue) -> Result<Option<RootedTraceableBox<Heap<*mut JSObject>>>, ()> {
Ok(Some(RootedTraceableBox::from_box(Heap::boxed(value.get().to_object()))))
}
}
```

build(cmake): detect python binary for specified version
<!-- Please describe your changes on the following line: -->
This PR aims to address #20268, by updating cmake definition to lookup python binary to use. Instead of directly asking `python` binary, this PR uses `${PYTHON_EXECUTABLE}` to lookup desired python binary where applicable.
This PR was locally tested on win32 / mac / arch linux via `mach build --dev`, so far local testing shows no build failure regressions, not sure if this is sufficient test.
