radv: reject binding buffer/image when the device memory is too small
>From the Vulkan spec 1.2.181:
"The difference of the size of memory and memoryOffset must be
greater than or equal to the size member of the
VkMemoryRequirements structure returned from a call to
vkGetImageMemoryRequirements with the same image"
This is invalid usage but adding a check in the driver is safe and
might avoid spurious failures.
This is a workaround for the inventory GPU hang with Cyberpunk 2077
which is actually a game bug. Luckily the game handles this error
gracefully.
Since the addrlib change from March, addrlib now selects a better
swizzle mode (4KB instead of 64KB) which reduces image size. Though,
the game assumes that an image with 2 mips is always smaller than the
same image but with 6 mips. This is not always true if the swizzle mode
is different. Then, it creates a D312 heap that is too small for the 2
mips image and the GPU hang with a memory violation, ugh...
Note that next vkd3d-proton release should also reject this but
fixing both sides is fine.
