Minimal rename of Origin-Isolation

This CL renames the Origin-Isolation header to Origin-Agent-Cluster, and
the window.originIsolated getter to window.originAgentCluster, following
whatwg/html#6214.

See Intent to Ship update at
https://groups.google.com/a/chromium.org/g/blink-dev/c/WW4fGjvroWI/m/bwxj0iiYAgAJ

This only does the minimal renames necessary to update web-facing
semantics, and then the minimal modifications to the tests to get them
passing again. Future CLs on top of this one should:

* Update all code references (e.g. function and member names) to stop
  saying "origin isolation".

* Update all test titles, comments, etc.

* Move the tests to a new directory.
