    schemas: Add tablet/stylus/pad schemas
    
    Compared to the g-s-d schemas, there's a few notable differences:
    
    - There are no compositor actions for rings/strips, with the libinput
      driver this is rather seen as a continuous axis, so we can't tell
      much about how it's being made discrete. It is preferred that clients
      manage the related pad events.
    - Tablet area is interpreted as an array of four 0..1 doubles, being
      each of those the padding on one side, relative to the full output
      size. We can no longer use values relative to the device resolution,
      because it might not be available.
    - Button mapping has been split into "primary" and "secondary"
      button settings, rather than an array of button numbers. The allowed
      values are now an enum, as button numbers are troublesome (especially
      the [4-7] scrolling button range, which can't be made to work on
      wayland)
