DDraw: Use HEAP_ZERO_MEMORY

[Stefan Dösinger]

When I wrote the new ddraw lib I thought HEAP_ZERO_MEMORY == 0 and HeapAlloc 
always intializes the alllocated mem. Apparently This isn't the case, so 
games crash after extending the structures(e.g. multithreading patches). Use 
the HEAP_ZERO_MEMORY flag when allocating object implementation structures.
