[Static Runtime] Schema checks for index_put (#84152)

Summary:
`index_put` can take a list of tensors, but Static Runtime always tries to convert its argument to a list of optional tensors. This was causing crashes for some users. Add some schema checks to prevent this, and add a new overload for the new case.

Also, I found a clear bug in the JIT interpreter (mutating the argument when its not supposed to), so I fixed that too.

Test Plan: New unit test
