Revert of [ExtensionView] Add extension id whitelisting for ExtensionView. (patchset #3 id:100001 of https://codereview.chromium.org/1419143009/ )

Reason for revert:
Reverting due to global variable (sizes regression).

Original issue's description:
> [ExtensionView] Add extension id whitelisting for ExtensionView.
>
> Per discussion with Chrome Eng Review, all extension ids that can be loaded by ExtensionView will be explicitly whitelisted in extension_view_whitelist.cc/h.
>
> This change whitelists the extension id used in browser tests, as well extension ids related to Media Router.
>
> This also removes some old logging and simplifies the test skeleton extensions.
>
> BUG=552207, 552208
