LinuxKPI-based DRM ports: move to new ports nomenclature.

After some discussions within the x11 team, it was decided to move to a new
nomenclature for the LinuxKPI-based DRM ports that correctly reflects the
FreeBSD version the ports are for. This will also allow us to move to dedicated
branches per FreeBSD release and eases porting work.

Functionally, this commit is a no-op as we are not moving to new snapshots.

Reflect the move in UPDATING and MOVED. Users using the graphics/drm-kmod meta
port should not be affected. Direct consumers of the DRM ports shall move, as
in MOVED, as follows:

drm-stable-kmod is drm-fbsd11.2-kmod
drm-next-kmod is drm-fbsd12.0-kmod
drm-devel-kmod is drm-current-kmod

new port: graphics/drm-stable-kmod

This is a repo copy of the last 4.9 status of graphics/drm-next-kmod. While
drm-next-kmod serves as the experimental DRM/KMS port, this new port will always
trail it and be in a more stable state. This is not a guarantee that
drm-stable-kmod will receive all versions from drm-next-kmod, more likely there
will be jumps.

Mark the two ports as mutually conflicting.

New port: graphics/drm-next-kmod.

This port includes the current state of the FreeBSDDesktop drm-next efforts to
port Linux DRM/KMS components to FreeBSD via the linuxkpi. This version of the
port incorporates Linux 4.9 code and works for amdgpu (HD7000/Tahiti and newer)
and i915 (HD3000/Sandy Bridge and newer) on recent FreeBSD HEAD.

A lot of people helped to make this happen by testing and reporting bugs.
However, very special acknowledgements are in order for kip, markj, hselasky,
kwm, Johannes Lundberg, and Pete Wright.
