target/arm: Add ID_AA64ZFR0_EL1.B16B16 to the exposed-to-userspace set

In kernel commit 5d5b4e8c2d9ec ("arm64/sve: Report FEAT_SVE_B16B16 to
userspace") Linux added ID_AA64ZFR0_el1.B16B16 to the set of ID
register fields which it exposes to userspace.  Update our
exported_bits mask to include this.

(This doesn't yet change any behaviour for us, because we don't yet
have any CPUs that implement this feature, which is part of SVE2.)
