Fix SFR swapchain test's implicit layout transitions

Fix SFR swapchain test's implicit layout transitions

The Vulkan spec says that layout transitions done on peer bound
image memory requires the implementation to support
VK_PEER_MEMORY_FEATURE_GENERIC_SRC_BIT and
VK_PEER_MEMORY_FEATURE_GENERIC_DST_BIT. The test never checked
for this capability and did implicit render pass layout
transitions anyway.

This CL updates the test to use an explicit layout transitions
on local aliases of the image when the implementation doesn't
support doing peer-to-peer transfer.

This CL also fixes a bug in the SFR rects definition in
VkBindImageMemoryDeviceGroupInfo to specify the correct number
of rectangles.

Affects:

dEQP-VK.wsi.win32.swapchain.render.*
dEQP-VK.wsi.win32.swapchain.modify.*
