Move macOS WPT chunk 1 (only) from Buildbot to Taskcluster
This is only one chunk at a time so that we don’t need to double the number of worker nor the cycle time during the migration.
A release build takes ~40 minutes which seems worrying, but this also happens (sometimes) on Buildbot. For example: https://build.servo.org/builders/mac-rel-wpt1/builds/10401

Initialize iframe viewport immediately
This is probably a significant cause of unstable test results, and it finally bothered me enough to fix it. The solution isn't great for performance (a sync layout query every time a iframe is added to a document), but performance needs to follow correctness.
