vkd3d-common: Merge vkd3d_debug.h into vkd3d_common.h.

There doesn't seem much point in separating these. Pretty much all of
vkd3d (eventually) includes vkd3d_debug.h, and vkd3d_debug.h includes
vkd3d_common.h because it uses VKD3D_PRINTF_FUNC. The separation also
makes it inconvenient to use the debug macros in vkd3d_common.h.
