ExchEcpVirtualDirectory and ExchOwaVirtualDirectory: missing OAuthAuthentication property

[MrBookie7]

Problem description

The ExchEcpVirtualDirectory and ExchOwaVirtualDirectory resources do not have the OAuthAuthentication property available. This was added in Exchange Server 2019 CU14 gaining support for HMA with ECP and OWA.
