Add a test to cover dr_create_memory_dump() for WIN32 and X32.

[ivankyluk]

#7047 adds X86 Linux support to dr_create_memory_dump(). The PR also adds a test to cover WIN32 and X64.

When the same test ran in vs2019-32, it crashed with the following error:

133: Test command: D:\a\dynamorio\dynamorio\build_debug-internal-32\bin32\drrun.exe "-s" "90" "-quiet" "-debug" "-use_dll" "D:/a/dynamorio/dynamorio/build_debug-internal-32/lib32/debug/dynamorio.dll" "-exit0" "-stderr_mask" "0xC" "-msgbox_mask" "0" "-dumpcore_mask" "0x7d" "-staged" "-code_api" "-c" "D:/a/dynamorio/dynamorio/build_debug-internal-32/suite/tests/bin/client.memory_dump_test.dll.dll" "--" "D:/a/dynamorio/dynamorio/build_debug-internal-32/suite/tests/bin/simple_app.exe"
