Add additional tests for VK_KHR_dynamic_rendering

Add additional tests for VK_KHR_dynamic_rendering

Change testing:

In one primary command buffer, record two render pass instances,
with the second resuming the first. In the first, draw one triangle
directly in the primary command buffer. For the second,
use CONTENTS_SECONDARY_COMMAND_BUFFER_BIT_KHR, draw the second
triangle in a secondary command buffer, and execute it in that
second render pass instance.

in a secondary command buffer, and execute it in that first render pass
instance. In second, draw one triangle directly in primary command buffer.
