I'm sure they've always made 4wd as long as they made trucks. and as long as they started making Silverados and Sierras

Not always from the factory.
Back in the '50/60s to get a 4wd GM truck it was a NAPCO conversion.

I Think the (A4WD) is automatic four wheel drive.
GM`s autotrac system.
I think 1999 with the introduction of the 800 series trucks was the first use of the system.
