Subject: [PATCH] enc_neon: enable vld1q_u8_x4 for clang & msvc

This restores the use of the function after
980b708e enc_neon: fix build w/aarch64 gcc < 9.4.0

The intrinsic was added to llvm for aarch64 in:
5e4ce1ae9dad Implement the newly added AArch64 ACLE functions for
             ld1/st1 with 2/3/4 vectors. The functions are like:
             vst1_s8_x2 ...
llvmorg-3.4.0-rc1~101
https://github.com/llvm/llvm-project/commit/5e4ce1ae9dad

Visual Studio 2019 and 2022 also support the function (2017 is still
disabled for this path due to it relying on arm64_neon.h).
