[clang] [Clang][AArch64]Remove _single from vg2x1 and vg4x1 svmla (PR #166799)

[via cfe-commits]

https://github.com/CarolineConcatto created https://github.com/llvm/llvm-project/pull/166799

This patch follows the PR#421[1] from the ACLE

These 2 FP8 intrinsics had single removed from them: from ``svmla[_single]_za16[_mf8]_vg2x1_fpm`` to ``svmla_za16[_mf8]_vg2x1_fpm`` and  from ``svmla[_single]_za32[_mf8]_vg4x1_fpm`` to  ``svmla_za32[_mf8]_vg4x1_fpm``
