Measure LocalLayoutContexts in LayoutTask and LayoutWorkers.

Browse source 
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.
