Improve setting up rd.xml and NativeAOT.Console.targets

[flibitijibibo]

Oh hey, a very rare instance where a console issue can be public!

One of the sketchier things we have to do for setting up a console port is manually editing our template rd.xml and occasionally editing the ilc.exe parameters for our custom .targets file - we should change it so games don't have to screw around with the NativeAOT branches so much:

• rd.xml should use RdXmlFile msbuild group instead of a custom path
• Console.targets should pull native imports from DirectPInvoke group
• For localized resources Console.targets should check IlcSatelliteAssembly group
• Console.targets should include IlcArgs group for custom arguments
• Document making a new .sln from the console samples (maybe a generator...? I dunno)

Do the above for...

• Switch
• Xbox
• PlayStation

The ilc args are done this way, for upstream targets:

Tested with RL1 and it works, so we should be able to reuse this for our targets file:
