Latest COG w/DRM backend has no focus

[vrazzer]

Latest COG w/DRM backend viewport does not receive focus. As a result, all focus related operations fail. Was driving me crazy as though it was a bug in spatial navigation. The new cog-viewport.c:cog_viewport_set_visible_view_internal() function seems the culprit and appear to contain two bugs:

#1- missing call to wpe_view_backend_add_activity_state(backend, wpe_view_activity_state_focused) in the enable section.

#2- the preceding disable logic test looks backwards (seems like it should test for !priv->visible_view).

Thanks.

Ignore #2. Looks pretty dubious, but crashes if you change it. Since DRM is single-window, not a case I can properly test.

Found the comment in cog_viewport_set_visible_view() which explains the focus issue. As setting focus is now the responsibility of the platform, calling wpe_view_backend_add_activity_state(wpe_view_data.backend, wpe_view_activity_state_focused) from cog_drm_platform_init_web_view() resolves the issue for DRM.
