Adding @@extension_id reserved message to l10n message map for extension.

It's added outside of ExtensionMessageBundle so that non-localized extensions can use it. Developer doesn't have to define default_locale in the manifest in order to get it working.

With this change every extension css file will go through message replacement process (only localized extensions went through that before).

This change will allow following construct in extension css:

body {

  background-image:url('chrome-extension://__MSG_@@extension_id__/background.png');

}

BUG=35208
TEST=Add an background image to your extension, and refer to it from css file using __MSG_@@extension_id__. Image should show up in the background.
