TextureVk: Don't transition to UNDEFINED in queue transitions.

When an imported texture with layout UNDEFINED was never used and then
exported with target layout UNDEFINED, Dawn would create a queue
transition barrier with dstLayout UNDEFINED which is not allowed by the
Vulkan specification. Instead detect this case and transition to
GENERAL.

Found by running dawn_end2end_tests with the VLL.
