Measure LocalLayoutContexts in LayoutTask and LayoutWorkers.
The FreeType instances in layout workers are reasonably large and worth measuring. The one in LayoutTask is smaller but it's easy to measure at the same time. Sample output: ``` | 8.33 MiB -- pages | 8.33 MiB -- url(file:///home/njn/moz/servo/../servo-static-suite/wikipedia/Guardians%20of%20the%20Galaxy%20(film)%20-%20Wikipedia,%20the%20free%20encyclopedia.html) | 1.32 MiB -- layout-worker-0-local-context | 1.31 MiB -- layout-worker-1-local-context | 1.24 MiB -- layout-worker-3-local-context | 1.17 MiB -- layout-worker-4-local-context | 1.08 MiB -- layout-worker-2-local-context | 1.06 MiB -- layout-worker-5-local-context | 0.78 MiB -- paint-task | 0.78 MiB -- buffer-map | 0.38 MiB -- layout-task | 0.30 MiB -- display-list | 0.07 MiB -- local-context ``` This required adding a mechanism to WorkQueue to measure worker TLSes.
