layers:Handle secondary cmd buffer transitions

When recording a secondary command buffer into a primary command buffer
record any image layout transitions from the secondary cb into the
primary cb.

At QueueSubmit time we validate the layouts at the primary cmd buffer
level so this change will allow that code to correctly work if
layout transitions occur in the secondary command buffer.
