  [CLANG][LLVM][AArch64]Add SME2.1 intrinsics for MOVAZ array to vector (#88901)

According to the specification in
    ARM-software/acle#309 this adds the intrinsics

    Move and zero multiple ZA single-vector groups to vector registers

    // Variants are also available for _za8_u8, _za16_s16, _za16_u16,
    // _za16_f16, _za16_bf16, _za32_s32, _za32_u32, _za32_f32,
    // _za64_s64, _za64_u64 and _za64_f64
    svint8x2_t svreadz_za8_s8_vg1x2(uint32_t slice)
    __arm_streaming __arm_inout("za");
