There are many variants of it, and the most popular example is probably a JEM. But where did it come from?

Condoms, for all the copious amounts of pussy with which you will be inevitably bombarded from this moment onward.

Steve Vai designed it...or helped with the design...something like that.

I believe Vai came up with it, to resemble his history in music or something like that. You could probably find his reasoning for it on his site.
I'm not a huge fan of the schecters inlays, its okay though.

Edwards CY-165CTM

The earliest vines I've seen on instruments are on the sides of the bodies of Cremonese violins, so I'd put the origin at the 16th or 17th century. Gibson was heavily influenced by violin luthiery, so you'll see Gibson mandolins from 1880 or 1890 that have vine inlays on the fretboard, which is the earlest fretboard vine inlay I'm aware of. From there it was probably used on a few Gibson acoustic guitars, and then made its way to electrics and eventually the JEM.

As far as where the Italians got the idea to put vines on instruments, I'm not sure. My first thought would be a Moslem influence via Spain, but that's just a guess.

Point is, Steve Vai was definitely not the originator of the vine inlay idea.
