aarch64: Use type-qualified builtins for [R]SUBHN[2] Neon intrinsics

Declare unsigned type-qualified builtins and use them to implement
(rounding) halving-narrowing-subtract Neon intrinsics. This removes
the need for many casts in arm_neon.h.

gcc/ChangeLog:

2021-11-09  Jonathan Wright  <jonathan.wright@arm.com>

	* config/aarch64/aarch64-simd-builtins.def: Declare unsigned
	builtins for [r]subhn[2].
	* config/aarch64/arm_neon.h (vsubhn_s16): Remove unnecessary
	cast.
	(vsubhn_s32): Likewise.
	(vsubhn_s64): Likewise.
	(vsubhn_u16): Use type-qualified builtin and remove casts.
