[PATCH 01/13] drm/vkms: Extract vkms_connector header

["José Expósito" <jose.exposito89@gmail.com>]

Up until now, the logic to manage connectors was in vkms_output.c.

Since more options will be added to connectors in the future, extract
the code to its own file.

Refactor, no functional changes.
