[PATCH v2 1/1] ntdll/tests: Minimize the stack size for test_tp_multi_wait().

[Francois Gouget]

From: Francois Gouget

This test creates 512 threads so the default 2 MB stack size requires
1 GB which can cause out-of-virtual-memory-space issues. So cause
threadpool to use the smallest possible stack size, which should be
1 MB, halving the virtual memory usage.

The dinput:device8 failure is a preexisting issue (see bug 54594).
