anv: Add field anv_image::planes[]::bo_is_owned (v2)

If this flag is set, then the image and the 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 during the same
call, vkCreateImage.

v2: Rebase onto VK_KHR_bind_memory2.
