  Log Message:
  -----------
  [ARM][AARCH64][NEON]: Wrong return type of NEON intrinsic  vqrshrunh_n_s16, vqrshruns_n_s32, and vqrshrund_n_s64 in arm_neon.h (#80819)

* fixes https://github.com/llvm/llvm-project/issues/71751
* changed return types in the table gen file responsible for generation
  of the problematic intrinsics
* this is to ensure that the return type for the functions is the same
  as specified in the Arm Developer Documentation and avoid casting
bugs

(https://developer.arm.com/architectures/instruction-sets/intrinsics/vqrshrunh_n_s16)
* updated lit tests to reflect the change in return type, worth noting
  that LLVM does not seems to differentiate signed and unsigned ints in
the IR, hence the change in type cannot be checked in IR as far as I am
aware
