[TIMOB-26960] Windows: Add TLS 1.3 support

*Summary:* Titanium iOS and Android to add support for TLS 1.3. Support it for Windows when possible. We should also make sure TLS 1.3 is enabled by default. *Requirements:* * Add a new TLS_VERSION_1_3 constant to [Ti.Network](https://docs.appcelerator.com/platform/latest/#!/api/Titanium.Network) module. * Add support for the new TLS version constant to [HTTPClient.tlsVersion](https://docs.appcelerator.com/platform/latest/#!/api/Titanium.Network.HTTPClient-property-tlsVersion) property. Note: Windows UWP does not support TLS 1.3 yet. See also https://docs.microsoft.com/en-us/uwp/api/windows.networking.sockets.socketprotectionlevel
