Multi-screen handling for the eglfs_kms_egldevice backend
Separates the generic kms classes into a own kms static lib called QtEglFsKmsSupport. The eglfs_kms plugin was changed to use these base classes and got renamed accordingly to QEglFSKmsGbm*. The eglfs_kms_egldevice plugin got extended to also derive from the kms base classed and by this provides multi-screen support Change-Id: I6de6a754e94cb8d52cf8e658b03c6bd6637674a1 Reviewed-by: Laszlo Agocs <laszlo.agocs@theqtcompany.com>
