[PATCH vkd3d 2/7] vkd3d: Add DXGI_FORMAT_UNKNOWN to the array of vkd3d_format objects.

[Conor McCarthy]

This results in a valid format instead of NULL being returned for
buffers and any other case where DXGI_FORMAT_UNKNOWN is specified.
In some cases invalid use of a buffer or DXGI_FORMAT_UNKNOWN will
not result in E_INVALIDARG, and would need to be tested explicitly
if proven to be an issue.
