[accessibility] Extension toolbar and infobar container views should not have state visible if they are not rendered on screen.

Add the ROLE_PANE role to viewsaccessibility types.

Provide accessible role and name for BrowserActionsContainer, InfoBarContainer, and InfoBar.

Set BrowserActionsContainer view visibility to true only when it contains browser actions.

Set ExtensionShelf vew visibility to true only when it has non-zero height.
