[Clang][LLVM][SVE2.1] Created intrinsics for DUPQ instr. (#83260)

This patch adds clang and llvm support for following intrinsic and maps
it to DUPQ instruction:
```
   // Variants are also available for:
   // _s8, _u16, _s16, _u32, _s32, _u64, _s64
   // _bf16, _f16, _f32, _f64
   svuint8_t svdup_laneq[_u8](svuint8_t zn, uint64_t imm_idx);
```
