Use ExtensionTabUtil::OpenOptionsPage to open IME option page.

window.open() was used to open the option page of IME extensions.
But this method can open more than one tab of the option page.
This cl change to use ExtensionTabUtil::OpenOptionsPage() to open the option
page.

In this change, ComponentExtensionIMEManager::IsComponentExtensionIMEId is moved
to extension_ime_util::IsComponentExtensionIME.
