JIT: retype byrefs passed to unmanaged callers as native int (#39105)

Make the jit more robust in cases where the IL producer is passing a byref
to an unmanaged caller, by retyping the argument as native int.

Allows the jit to produce self-consistent GC info and avoid the issues
seen in #34279, at least for byrefs.

Closes #39040.
