Checkout Polymer using bower instead of the raw repository.

This adds Polymer to third_party using bower rather than the raw repository.
Bower is the recommended way to manage Polymer. It makes it easy to update
this dependency in chrome as well. Instructions for updating polymer are
included in the README.chromium file.

The existing references to polymer.min.js have been updated.

This change is so that more polymer components can easily be added which  are
needed for the PDF extension.

RulesRegistryWithCacheTest uses CHANNEL_UNKNOWN to access DWR API

(Was: Whitelist test extension in RulesRegistryWithCacheTest to use DWR API)

RulesRegistryWithCacheTest.RulesPreservedAcrossRestart needs to install an extension using declarative rules.
None of the APIs using declarative rules is available in stable yet, so this breaks tests on official builders.

This CL uses ScopedCurrentChannel to simulate being on the unknown channel (that's what Chromium builds use).

Alternative approaches:
 * Add a command line flag to whitelist the test extension for accessing the Declarative Web Request API. This was tried in patch sets 1-4 here, but abandoned in favour of ScopedCurrentChannel.
 * Make the test extension a component one (https://codereview.chromium.org/113993002/). That could have unwanted side effects.
