Auto merge of #20658 - kvark:deglify, r=emilio

Browse source 
Make gleam optional for compositor, switch various names from glutin to winit

<!-- Please describe your changes on the following line: -->
The PR goes an extra step towards discriminating GL to a level of an optional dependency. This would ease up the transition to gfx-hal when the time calls for it, and upstreams some of the patches we've been using locally, cleans up some of the old cruft along the way.

---
<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [x] `./mach build -d` does not report any errors
- [x] `./mach build-geckolib` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix #20612

<!-- Either: -->
- [ ] There are tests for these changes OR
- [ ] These changes do not require tests because _____ it's just refactoring

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->

<!-- Reviewable:start -->
