end2end_tests: Forward Windows debug messages to stderr

When validation layers are enabled, D3D12 warnings and error
messages are logged to the shared DBWIN_BUFFER segment of memory.
This CL has makes the test environment watch for new events and
logs them to stderr so they show up in the test bot logs. This helps
debug problems in the D3D12 backend which previously just crashed
with a general Device Lost message.
