dix: Move DeviceFocusEvent from Xi into enterleave.c

This is only called from the enterleave implementation, so move it and its
helper functions to there. No functional changes.

Fixes build error introduced in 31174565ec0090b4c03c9334c82878be2455f938 if
building with '-Werror=implicit-function-declaration'
