Update SDL version and support newer SDL mapping features

[offalynne]

Is there an existing issue for this?

• [X] I searched the existing issues and did not find anything similar.

Current Behavior

SDL mapping produces invalid GUIDs (and thus invalid mappings), keys added to newer SDL (including touchpad, misc button, paddles) are missing and can not be mapped, CRC field is missing

Expected Behavior

An up to date SDL version tested for proper interoperation with other software including Steam and myriad modern games

Steps To Reproduce

Create a gamepad mapping, observe format is out of date, mapping features are missing, and GUID is likely incorrect (compared to Steam and other apps using SDL)

Environment

Tested with Linux binary (issue is observable in any release/environment)

Anything else?
