ui: Move the support for touch inputs into RecoveryUI.

- Added detection for EV_ABS events in minui/events.cpp, if it's
  allowed;
- Added listening and processing touch inputs in ui.cpp;
- Fixed an issue in recognizing swipe with multi-touch protocol A;
- Changed the logic in RecoveryUI::ProcessKey() to be swipe-aware. It
  now allows turning on text mode with <power> + <swipe-up>.

The last change also fixed an issue on devices with protocol A: prior
to this CL, user may accidentally toggle the text mode during an OTA.
Because it was considered as a single-button device, a long tap that
sent BTN_TOUCH event would turn on text mode.

Test: Allow detecting touch inputs. Swiping (up, down, enter) works on
      angler, angelfish, dorado respectively.
