ApiCheck baselines need to be updated

[John Luo]

Missed updates to api check baselines seem more prevalent than I originally anticipated.

I've updated the Kestrel repo: aspnet/KestrelHttpServer#2959.

But now I see it in other repos as well:
https://github.com/aspnet/Hosting/blob/release/2.2/src/Microsoft.AspNetCore.Hosting/baseline.netcore.json#L2.
https://github.com/aspnet/IISIntegration/blob/release/2.2/src/Microsoft.AspNetCore.Server.IISIntegration/baseline.netcore.json#L2
https://github.com/aspnet/Security/blob/master/src/Microsoft.AspNetCore.Authorization/baseline.netcore.json#L2
https://github.com/aspnet/MetaPackages/blob/master/src/Microsoft.AspNetCore/baseline.netcore.json#L2

This is by no means an exhaustive list, I just took a quick look at a few of our repos. We should systematically scan through all of our repos to make sure everything is up to date.

Confirmed there are no breaking changes from 2.1 to 2.2 preview3 for these assemblies.
