Fix state binding in multiview tests

Fix state binding in multiview tests

According to the spec, when multiview is enabled all non-render pass
state is undefined at the beginning of each subpass, but multiview tests
were binding vertex buffers, index buffers and descriptor sets before
beginning the render pass. This commit moves the binding commands to the
same point the pipeline is bound for each subpass.

In addition, it fixes some validation errors related to the following
VUIDs:

  - VUID-VkSubpassDependency-srcSubpass-02243
  - VUID-VkSubpassDependency2-srcSubpass-02245

Due to some subpass dependencies missing the VK_DEPENDENCY_BY_REGION_BIT
bit in their flags despite being mandated by the spec.

Affected tests:
dEQP-VK.multiview.*

Components: Vulkan
VK-GL-CTS issue: 3701
