btrfs-progs: add the incompat flag for extent tree v2 

I will have a lot of preparatory patches to reduce the review pain of
this large feature.  In order to enable that work define the incompat
flag.  Once all of the work lands to support the feature there will be a
patch to actually enable us to select it and manipulate file systems
with that incompat flag set.
