ISSUE-20455: introduce stronger types for textinput indexing
<!-- Please describe your changes on the following line: -->
Added two new types:
- ByteOffset
- UTF16CodeUnitOffset
I've replaced any instance of `usize` that would be better represented by one or the other of these. I also updated any downstream code, including the unit tests for `textinput.rs`. Along the way, I tried to add or edit comments to better reflect my understanding of this file - happy to revisit if I have misrepresented anything.
I did not end up finding any places where types were very obviously being mixed, as the issue description suggested I should do... LMK if I should re-audit the file for that (might need a bit of guidance)!

Add initial support for WebGL compressed textures
This patch is an initial implementation of WebGL compressed texture support, it contains
- functions for registering and querying compressed texture extensions
- initial implementation of `CompressedTexImage2D` and `CompressedTexSubImage2D` and their parameter validation
- implementation of S3TC (DXT1, DXT3, DXT5) and ETC1 extensions as examples
What's still missing:
- some of the parameter validation steps are missing
- the pixel comparison tests fail for more complex cases (I'm probably missing something trivial at the GL calls)

spec update: window.name deals with lack of browsing context
<!-- Please describe your changes on the following line: -->
new [spec](https://html.spec.whatwg.org/multipage/window-object.html#dom-name):
The name attribute's getter must run these steps:
1. If this Window object's browsing context is null, then return the empty string.
2. Return this Window object's browsing context's name.
The name attribute's setter must run these steps:
1. If this Window object's browsing context is null, then return.
2. Set this Window object's browsing context's name to the given value.
What is `null` here? According to [spec](https://html.spec.whatwg.org/multipage/browsers.html#concept-document-bc)
> A Document's browsing context is the browsing context whose session history contains the Document, if any such browsing context exists and has not been discarded, and null otherwise.

Implement connectStart in PerformanceResourceTiming
<!-- Please describe your changes on the following line: -->
- Added connectStart where needed (```ResourceFetchTiming```, ```ResourceAttribute```) in ```components/net_traits/lib.rs ```
- Before calling ```client.request``` in ```obtain_response```, we now add the ```connectStart``` attribute (```components/net/http_loader.rs```)
- Updated tests to reflect those changes

Fix modes for fetching classic worker script and introduce parser metadata for request
While reading [the spec](https://html.spec.whatwg.org/multipage/#fetch-a-classic-worker-script) for `fetch a classic worker script`, I found the `mode` and `credential-mode` are opposite to the spec. So, the first commit will fix it.
Also, I found there's a `parser metadata` for `request` so I tried to introduce it in this PR as well.
For WPT, I found there's a `/workers/constructors/Worker/same-origin.html` which was disabled in #3180. We pass most of the tests now.

Support WorkerOptions for Worker
I'd like to start working on updating SW related codes and I found it will have some algorithms related to module workers. And I found parts of the spec update is related to [fetch a module worker script graph](https://html.spec.whatwg.org/multipage/#fetch-a-module-worker-script-tree), maybe it's worth being a separate PR?

Add optional ANGLE support to glutin port
Supporting ANGLE in Servo has two important benefits:
* we can actually run Servo instances on our Windows CI machines, which gives us more confidence that we're not breaking it
* we can continue to use OpenGL on devices like the Hololens, rather than creating platform-specific graphical backends
