Investigate Windows CI testPlatformOptionsRunAsUser failure

[iCharlesHu]

On Windows CI, testPlatformOptionsRunAsUser sporadically fails with Caught error: Failed to spawn the new process with underlying error: UnderlyingError(rawValue: 1326) which I can't reproduce locally.

Error 1326 is

ERROR_LOGON_FAILURE
1326 (0x52E)
The user name or password is incorrect.

This could indicate some sort of permission issue that CI imposes. Disable the test for now to unblock other PRs.

I think this is a timing issue. There's no way to programmatically wait until the user has finished being created; there is still some async work that happens after NetUserAdd. Best thing to do is probably to retry in a loop every time ERROR_LOGON_FAILURE is seen, up to some timeout (30 seconds?)
