Enzyme v0.12.17 fails the DifferentiationInterface test suite

[gdalle]

The new version v0.12.17 fails DI tests which used to pass before, as I realized in a completely unrelated PR (JuliaDiff/DifferentiationInterface.jl#327).

Something is wrong with the part of our tests related to the pullback of a scalar-to-vector function, said pullback now returns 0 instead of the correct result.

MWE (needs the main branch of the DI repo, not the latest release):

using Pkg

Pkg.add(["ForwardDiff", "Enzyme"])

Pkg.add(
    url="https://github.com/gdalle/DifferentiationInterface.jl",
    subdir="DifferentiationInterface"
)
    
Pkg.add(
    url="https://github.com/gdalle/DifferentiationInterface.jl",
    subdir="DifferentiationInterfaceTest"
)

import ForwardDiff, Enzyme
using DifferentiationInterface, DifferentiationInterfaceTest

f = DifferentiationInterfaceTest.num_to_arr_vector
x = 1.0
dy = float.(1:6)

julia> pullback(f, AutoForwardDiff(), x, dy)
21.1651695124516

julia> pullback(f, AutoEnzyme(), x, dy)
0.0

This was the result of a bad jll uptake yesterday and has been fixed on main (and being released today)
