[Mesa-dev] [PATCH 16/20] anv: Add field anv_image::bo_is_owned

[Chad Versace]

From: Chad Versace <chadversary at chromium.org>

If this flag is set, then the image and it's bo have the same
lifetime. vkDestroyImage will release the bo.

We need this for VK_ANDROID_native_buffer, because that extension
creates the VkImage and imports its memory in the same call,
vkCreateImage.
