[video_core/vic] remove handrolled vector implementation that also uses software prefetching(!!!!); don't try to outsmart compiler - also remove template spam (#2856)

Also removes sse2neon :)
Software prefetching SUCKS and it's evil don't do it

-Subject: [PATCH] Add support for clang-cl on Windows (#633)
-
-This commit adds support for clang-cl (clang, pretending to be MSVC) to
-SSE2NEON on Windows ARM64 platforms. This change is part of some Blender
-work, as using clang-cl provides a ~20-40% speedup compared to MSVC.
-
-Compiled with the following command line (via a VS2022 Native ARM64 Tools
-CMD window):
-  msbuild sse2neon.vcxproj /p:Configuration=Release /p:CLToolExe=clang-cl.exe
-                           /p:CLToolPath="C:\Program Files\LLVM\bin\"
-
-Known failures in test suite:
-  Test mm_cvttpd_epi32
-  Test rdtsc
