Test transitions between command buffer states

Test transitions between command buffer states

This change adds tests that drive command buffer state
transitions that weren't covered by existing tests.
This change also corrects record_many_secondary test that
previously was not operating on secondary command buffer
(it had the same source as record_many_primary).

Components: Vulkan

VK-GL-CTS issue: 802

Affects:
dEQP-VK.api.command_buffers.*_to_ininitial
dEQP-VK.api.command_buffers.record_single_secondary
