[PATCH vkd3d] tests: Include <stddef.h> from "d3d12_crosstest.h".

[Chip Davis]

Neither MinGW's nor Microsoft's <windows.h> includes <stddef.h>, either
directly or indirectly.

Fixes cross compilation errors related to using offsetof(3).

To answer Henri's question: I'm using somewhat ancient Clang 10.0 that was compiled from Git. This is the error I see building crosstests:

tests/d3d12.c:23900:13: warning: implicit declaration of function 'offsetof' is
      invalid in C99 [-Wimplicit-function-declaration]
            offsetof(struct argument_data, dispatch), NULL, 0);
            ^

Oh, that makes sense. (But "Clang" isn't quite "MinGW"; MinGW/gcc
pulls in stddef.h through inttypes.h here.) Could you resend this with
an updated commit message?
