dependencies: Upgrade to WebRender 0.64 (#31486)
This brings the version of WebRender used in Servo up-to-date with Gecko upstream. The big change here is that HiDPI is no longer handled via WebRender. Instead this happens via a scale applied to the root layer in the compositor. In addition to this change, various changes are made to Servo to adapt to the new WebRender API.
