introduce web_components pkg to replace shadow_dom, html_import, custom_element. This new package is 100% compatible with the polyfills used by http://www.polymer-project.org/

Deletes:
  pkg/shadow_dom
  pkg/custom_element (except web_ui stuff)
  pkg/html_import

Adds:
  pkg/web_components, with README.md and build instructions

Changes:
  pkg/html5lib -- deprecate queryAll/query in favor of *Selector
  pkg/polymer -- test fixes & a few small changes to work with new polyfills, mostly in build
  tests/html/custom -- can't load the CE polyfill at runtime, must now be injected statically via an HTML page, similar to the style @blois used for some custom element tests.

This is like [unorderedEquals], but it instead takes an iterable of
matchers and asserts that elements in the actual value match the
matchers.

BUILDBOT_BUILDERNAME is only set for bots using annotated steps, which
isn't all of them. This detects whether the username is "chrome-bot"
instead.

This check is currently only being used to decide whether to use
unittest's compact VM config or the default config.
