Support the community standard `defer-hydration` attribute

[zachleat]

This will allow us to avoid the node renaming mechanism for lazy custom element hydration, which will be much faster.

Proposal: webcomponents-cg/community-protocols#15

Currently this requires component authors to add support for this attribute to their component code. is-land takes the task of removing the attribute when the island is ready.

Awesome! Was planning to make a PR / file an issue about this after our discussion, but looks like you beat me to it. 😁
