Wrong return type in some ARM NEON intrinsics

[yyctw]

Documentation: https://developer.arm.com/architectures/instruction-sets/intrinsics/#f:@navigationhierarchiessimdisa=[Neon]&q=qshrun_high_n
According to the ARM NEON documentation, the return type of vqshrun_high_n_s{16/32/64} should be uint. However, in the arm_neon.h file, the return type of these functions is int. It caused an compilation error similar to the previous issue #71362 when using the -fno-lax-vector-conversions flag.

Clang version:

Debian clang version 15.0.7
Target: x86_64-pc-linux-gnu
Thread model: posix
