Currently, this feature is implemented only on Linux and macOS (see also bug 1077515 and bug 1301497), and the code is really similar each other. Additionally, it always tries to query selection to check whether the caret is in vertical content or not if arrow keys are pressed. For avoiding a lot of query, this patch makes `TextEventDispatcher` cache writing mode at every selection change notification. However, unfortunately, it's not available when non-editable content has focus, but it should be out of scope of this bug since it requires a lot of changes. Anyway, with this patch, we can write a mochitest only on Linux and macOS. The following patch adds a test for this as a fix of bug 1103374.
