Summary:
Set xkb context and keymap to Ecore_Drm.
In enlightenment (used in wayland with drm backend), keymap is used only one.
So for avoid unnecessary open keymap files, set cached context and keymap.
But for this, enlightenment must compile keymap before init ecore_drm.
So I changed booting sequence also.
Test Plan: Distinguish time between before and after during add a keyboard device.

it is now possible to create a xephyr window in a drm-enlightenment session,
launch wl-x11 enlightenment in xephyr, and then launch wl-wl enlightenment
inside that enlightenment
the primary limitation on this output module is that all internal windows will
appear in the outer compositor due to the current restriction of ecore-wayland
with regard to only having a single global display server connection
