Wayland: Fix repeated key not released on defocus

Platform code should not generate key events with GLFW_REPEAT.
GLFW_PRESS is translated into GLFW_REPEAT by shared code based on the
key state cache.

This confused the automatic key release logic into not generating an
event with GLFW_RELEASE for a key being repeated when the window lost
input focus.

(cherry picked from commit 3f5dfeaf29)
