DOM: Implement `some()`, `every()`, `find()` Observable operators

This CL implements the following Observable operators:
 - some()
 - every()
 - find()

Their inclusion is to be consistent with Iterator helpers [1] and Async
iterator helpers [2], and is discussed in
https://github.com/WICG/observable/issues/126 and to a lesser extent
https://github.com/WICG/observable/issues/106.

See https://github.com/WICG/observable/pull/137 for the specification.
