Xamarin.Mac does not honor AOT options from IDE

[chamons]

@mykyta-bondarenko-gl Found a bug yesterday that was fixed in master as:

659a74c

but was fixed before the issue was actually filed. This is an after-the-fact issue for it, since it needs to be cherry picked to 15.7.

Xamarin.Mac currently accepts "mmp arguments" of "--aot=all|hybrid" in projects and AOTs, but if the project uses the IDE settings and generates project tags of AOTMode / HybridAOT they are ignored.

Steps to Reproduce

1. Create a new XM Project.
2. Enable AOT using the Mac Build pane.
3. Build - No AOT :(

Expected Behavior

The two option paths to work identically.

Environment

master / stable both have issue.

VS bug #598586
