Auto merge of #8227 - asajeffrey:versioned_dom, r=eefriedman
Versioned dom
This PR adds versioning to the DOM. There are now node.get_version and node.get_descendent_version methods that return a counter that is bumped when the node is dirtied. This is used to implement cache invalidation for caching HTMLCollection state. Caching HTMCollections gets a 1000x speedup in the Dromaeo DOM query tests.
Addresses https://github.com/servo/servo/issues/6901, https://github.com/servo/servo/issues/3381 and https://github.com/servo/servo/issues/1916.
