Steam: Check Valve Anti-Cheat status

[iampremo]

Originally a mantis suggestion, seems hand. Dont see anything in the manual that would allow this right now.

Function to check anti-cheat status of signed-in user

RK in 2016 (imagine the docs are different): Looking at the documentation from Valve this may be possible see https://partner.steamgames.com/documentation/auth particularly the section on
"Session Tickets between a game client and other clients or game servers" and the section on SteamUser()->GetAuthSessionTicket().

should probably be moved to https://github.com/YoYoGames/GMEXT-Steamworks/issues ?

[Infiland]

This appears to be implemented by merged PR #154: #154

That PR added the auth-session flow requested in this issue:

• steam_user_get_auth_session_ticket
• steam_user_begin_auth_session
• steam_user_end_auth_session
• validate_auth_ticket_response async event
• STEAMWORKS_AUTH_SESSION_RESPONSE, including VAC_BANNED, VAC_CHECK_TIMED_OUT, and PUBLISHER_ISSUED_BAN

The issue likely stayed open because the PR body used “Related to #150” instead of a closing keyword. I do not see a separate code change needed unless the request is for a different one-call helper around the current user's own status.
