  [Clang][AArch64][SVE2p3][SME2p3] Add intrinsics for v9.7a Two-way signed/unsigned absolute difference sum and accumulate long ops (#188972)

Add the following new clang intrinsics based on the ACLE specification
https://github.com/ARM-software/acle/pull/428 (Add alpha support for 9.7
data processing intrinsics)

SABAL (Two-way signed absolute difference sum and accumulate long)
- svint16_t svabal[_s16](svint16_t, svint8_t, svint8_t) / svint16_t
svabal[_n_s16](svint16_t, svint8_t, int8_t)
- svint32_t svabal[_s32](svint32_t, svint16_t, svint16_t) / svint32_t
svabal[_n_s32](svint32_t, svint16_t, int16_t)
- svint64_t svabal[_s64](svint64_t, svint32_t, svint32_t) / svint64_t
svabal[_n_s64](svint64_t, svint32_t, int32_t)

UABAL (Two-way unsigned absolute difference sum and accumulate long )
- svuint16_t svabal[_u16](svuint16_t, svuint8_t, svuint8_t) / svuint16_t
svabal[_n_u16](svuint16_t, svuint8_t, uint8_t)
- svuint32_t svabal[_u32](svuint32_t, svuint16_t, svuint16_t) /
svuint32_t svabal[_n_u32](svuint32_t, svuint16_t, uint16_t)
- svuint64_t svabal[_u64](svuint64_t, svuint32_t, svuint32_t) /
svuint64_t svabal[_n_u64](svuint64_t, svuint32_t, uint32_t)
