arm: fix __arm_vld1q_z* and __arm_vst1q_p* intrinsics [PR108442]

The MVE ACLE allows for __ARM_MVE_PRESERVE_USER_NAMESPACE to be defined,
which removes definitions for intrinsic functions without the __arm_
prefix. __arm_vld1q_z* and __arm_vst1q_p* are currently implemented via
calls to vldr* and vstr*, which results in several compile-time errors when
__ARM_MVE_PRESERVE_USER_NAMESPACE is defined. This patch replaces these
with calls to their prefixed counterparts, __arm_vldr* and __arm_str*,
and adds a test covering the definition of __ARM_MVE_PRESERVE_USER_NAMESPACE.

gcc/ChangeLog:

	* config/arm/arm_mve.h (__arm_vst1q_p_u8): Use prefixed intrinsic
	function.
