Add up/down page indicator to CMS menu display

Browse source 
Often the user doesn't realize that there are more menu items then displayed and the only way to tell was to try and move the selection to the bottom to see if another page appears.

This PR adds page up/down indicators if there are more menu items than those visible on the current display.

Uses the OSD arrow symbols when possible (for OSD supporting devices), otherwise the `^` (carat) and `V` are used for text-only represenatations.

To determine if the device was capable of displaying symbols the `displayPort` structure has a new `deviceType` set when it is initialized. There have been other times when knowing the type of device would have been useful so that's now supported. Then this is abstracted by a new `displaySupportsOsdSymbols()` function. Devices that support OSD are assumed to support the OSD symbols as the OSD element drawing code always uses them. For devices that don't support OSD function we have to presume the sybols aren't available.
