    d3d8/tests: Add a small test for multisampled CopyRects().

This commit causes the d3d8:visual to crash on my desktop (Debian 
Testing, 9600GT, 285.05.09-1 proprietary driver):

wine: Unhandled stack overflow at address 0x7e3ab8bf (thread 0009), starting debugger...
err:seh:setup_exception_record stack overflow 1100 bytes in thread 0009 eip 7ef8952b esp 00240ee4 stack 0x240000-0x241000-0x340000

The call that causes the crash is:

    hr = IDirect3DDevice8_CopyRects(device, rt, NULL, 0, readback, NULL);

The stack trace seems to point towards an out of hand recursion problem 
that eventually causes a stack overrun:
