D25663: Initial support for tablets on Wayland

  - I suppose this is related to T11660 <https://phabricator.kde.org/T11660>? If so relate the diff and the object.
  - Improve commit message, explain your future steps.
  - For touch events we already have a fallback to pointer events in KWayland in case the client does not support touch events. I would prefer that we follow the same pattern with tablet events. Otherwise argue why a input event filter is better suited in this case.
  - Adhere to styling rules. From what I have seen:
    - Line length
    - Brackets
    - Enum definition
  - libinput interfacing code looks good

There is a `input()->pointer()` getter. Remove member variable.

Do not use single letter variable names. Minimum two letters. Same below with `e`.

Implement or add a notice why these are commented out / a TODO.

Change to hash and getter in separate patch. Under the assumption we keep the new input event filter this needs to go into input.h/input.cpp or some other device-independent file and not anymore in pointer_input.
