  [AArch64] Don't generate neon integer complex numbers with +sve2. NFC (#79829)

The condition for allowing integer complex number support could also
allow neon fixed length complex numbers if +sve2 was specified. This
tightens the condition to only allow integer complex number support for
scalable vectors.

We could generalize this in the future to generate SVE intrinsics for
fixed-length vectors, but for the moment this opts for the simpler fix.
