Vulkan: Prefer BGR565 for RGB565 if enabled Some platforms exhibit better performance when using BGR565 instead of RGB565, including when loading buffer data to the image. This change allows such platforms to use a BGR565 image in the backend instead of an RGB565 image when using Vulkan, when the corresponding flag is enabled: preferBGR565ToRGB565 * Updated the formats to include B5G6R5 as a fallback to R5G6B5, which would be triggered when the corresponding feature flag is enabled. * The only exception would be when the surface is being initialized as R5G6B5. * In addition, this format will not be subject to forced format fallback. * Added VVL skip that specifically does not allow undefined format for border color for certain formats, including B5G6R5 if flag enabled. * Some suites with RGB565 tests will be run with preferBGR565ToRGB565 enabled on SwS to provide better test coverage.
