Fix errors in imageless framebuffer tests

Attachment must not be VK_ATTACHMENT_LOAD_OP_LOAD if initialLayout is
VK_IMAGE_LAYOUT_UNDEFINED
If framebuffer flags contain VK_FRAMEBUFFER_CREATE_IMAGELESS_BIT then
image usage must include VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT

Components: Vulkan

VK-GL-CTS issue: 3969

Affected tests:
dEQP-VK.imageless_framebuffer.*
