I've generally heard this called a "frito pie", though frito pie may
also be eaten without the bag.  Initial pokings suggest this goes back
to at least the 50s, though Frito-Lay claims 1932:

(a WSJ article that discusses this)

"According to Frito-Lay lore, Daisy Dean Doolin, mother
of Elmer Doolin, founder of the original Frito company, concocted the first
Frito pie in the kitchen of her San Antonio home in 1932 -- an attempt
to turn leftover chili into something more. Whatever the origins, the pie
had made its way to lunch counters and drive-ins by the 1950s. Now, it
is popular across a wide swath of middle America, prepared by the consumer,
or bought at mall food courts and the like. Some purists simply pour the
fixings into a bag of Fritos and shake."
