Previously, when the theme was set it was only set on currently active `Window`s. This change makes setting the `Theme` stateful. Now the `Constellation` tracks what theme is applied to a `WebView` and properly passes that value to new `Pipeline`s when they are constructed. In addition, the value is passed to layout when that is constructed as well. Testing: this change adds a unit test. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
