[PATCH 1/2] windows.devices.enumeration: Create stub DeviceAccessInformation class.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=124867

Your paranoid android.

[PATCH 2/2] windows.devices.enumeration: Add stub IDeviceAccessInformation interface.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=124868

Your paranoid android.

Would you mind adding a trailing comma?

Also I think the header changes should go in a separate commit.

Tbh, I feel like the `dai_` prefix is way too short. I know WinRT tends to be verbose but imho `device_access_information_` would be better.
