NativeSkiaOutputDeviceVulkan: Use minimal set of usage flags for VkImage
VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT usage flag is not necessary because
the native VkImage imported into QSG seems to be only accessed via
sampling. VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT also seems to conflict
with the VK_IMAGE_LAYOUT_UNDEFINED initial layout with Nvidia driver.
VK_IMAGE_LAYOUT_UNDEFINED is a requirement for importing external
texture from Chromium.
Keep VK_IMAGE_USAGE_SAMPLE_BIT usage flag because it is a requirement
for sampling.
Remove the corressponding VK_IMAGE_LAYOUT_PRINITIALIZED initial layout
workaround for Nvidia. It is not necessary without the
VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT flag and fixes validation layer
warning.
Also remove VK_IMAGE_USAGE_TRANSFER_DST_BIT and
VK_IMAGE_TRANSFER_SRC_BIT usage flags because those are not used and
seem to be leftover from an earlier implementation.
