v3dv: ignore barriers for image layout transitions from undefined layouts

v3dv: ignore barriers for image layout transitions from undefined layouts

Layout transitions are not relevant to us, we only care about barriers
that involve a sync point between read/write actions on the image across
GPU jobs.

Image transitions from undefined layout can only happen before the image
is ever used by the GPU, which means they are never relevant to our
implementation.

This improves performance in vkQuake.
