The test element-array-buffer-delete-recreate.html now fails because we don't
actually implement gl.getParameter(gl.CURRENT_PROGRAM).

Ports refactoring
Depends on https://github.com/servo/servo/pull/20071 and https://github.com/servo/servo/pull/19895
This PR does 3 things:
1) merge all the embedder coordinates callbacks into one
2) hand the embedder messages directly to the embedder
3) split the embedder code in 2 files: window.rs and browser.rs
This is in preparation for tabs support in `ports/`. We want to separate the windowing logic (glutin stuff) and the browsing logic (tabs management, browsers state, etc). It's also easier to bypass the callbacks and directly handle events.

fix(keyevent): do not emit default ignorable codepoint
<!-- Please describe your changes on the following line: -->
This PR intends to update `KeyEvent` emit behavior around #18130. Issue https://github.com/servo/servo/issues/17146#issue-233361568 briefly explains what's happening in servo currently - there are KeyboardInput event emitted for separated key (modifier, and `V` in case of paste) and there are also `ReceivedCharacter` event corresponds to `\u{0016}`.
`0x0016` is unicode representation of `Synchronous Idle` (https://en.wikipedia.org/wiki/Synchronous_Idle), belong under category of `Default Ignorable` charater in unicode range doesn't have visual representation (http://www.unicode.org/L2/L2002/02368-default-ignorable.pdf). Currently servo forwards all of emitted event from `winit` including this, eventually leads into double execution of control event.
In this change try to omit default ignorable charater , if given char received is within range of ignorable do not dispatch `KeyEvent`. Once those are omitted, current event handling logic already takes care of key event with correct modifier state so duplicated event handling won't occur.
For implementation perspective, `std::char` in Rust doesn't seem to support `isIdentifierIgnorable` like other platform does (i.e: https://msdn.microsoft.com/en-us/library/aa285330(v=vs.60).aspx / https://docs.oracle.com/javase/7/docs/api/java/lang/Character.html) - so does quick, naïve range comparison check based on unicode range specified in spec, similar to halfbuzz and other does. (https://github.com/harfbuzz/harfbuzz/blob/master/src/hb-unicode-private.hh#L134)
Lastly, this is indeed behavior of `winit` to emit all characters by default. *Why not try to make upstream changes instead?* While I've been reading through issues in `winit`, issue like https://github.com/tomaka/winit/issues/350 trying to emit ignorable character by its intention (delete key `ReceivedCharacter` is also under category of default ignorable) and let each consumer application handles it as needed. I assume it'll cause breaking changes in winit's design if it intends to omit those characters, instead tried to make application-level changes.
Couple of consideration for review
- Is it desired changes to not emit `KeyEvent` for default ignorable chars? Do we rather want mapping / or restoring back to original char as @paulrouget mentioned in https://github.com/servo/servo/issues/17146#issue-233361568?
- Any better, recommended approach to detect unicode char range?
- Maybe try to make upstream changes to `winit` still, like having configuratble way to opt-in(out) those char event?

refactor(counter_style): parse int via parse_non_negative
<!-- Please describe your changes on the following line: -->
Relates to #20332.
This PR intends to refactor `counter_style` to use `parse_non_negative` where applicable, mostly which uses `expect_integer` currently. Change still grabs value from parsed result then assign it into each struct as needed and does not change definition of struct (i.e `AdditiveTuple`) itself.
