GHOST/Keymap: support for detecting repeat events

- Keymap items now have 'repeat' boolean which can be set
  to make keymap items respond to key repeat events or not.
- Support for X11 & WIN32 (not macOS currently).

This allows for the possibility to perform actions while a key is held
and finish the action upon release.

Thanks to @Severin for review and WIN32 support.
