We only use it to get the quirks mode, and a shared style context is a pretty
heavy-weight struct.

Implement DOM to texture
<!-- Please describe your changes on the following line: -->
This is a prototype of the WebGL DOMToTexture feature. The API should be fine as a privileged extension for now due to security concerns. The working group has been investigating the viability of unprivileged usage but the spec is not ready yet.

I’m not confident of the implications regarding variance, dropck, struct
aliasing, etc. when this is extended to generic `*const T` and `*mut T`.
Release builds should use `unstable` to enable other optimizations anyway.
Remove use of unstable box syntax.
http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

fix windows build issue #18055
<!-- Please describe your changes on the following line: -->
With some reasons, the windows and VS environment do not set the `env("PLATFORM")` variable.
So, there's no need to check the variable, and set `os_type` equl to `pc-windows-msvc` as default. Then the script can get correct url to download `rustc`.

CEF: use `cargo rustc -C link-args=…` instead of `#[link_args="…"]`
The latter is an unstable feature that might be changed or removed.

style: Use left-to-right indices in the invalidator.
This will make easier to create external invalidations that don't point to a combinator,
and also makes reasoning about the invalidator a bit easier.
