Built in efficient vec2/3/4 types, everyone duplicates that

We had base2d and base3d as part if standard library but they were a little awkward and people did not like them. So they got moved out.

I have a library with vec2/3/4 types I can put up, but I feel like everyone would just write their own versions anyways.

well it's not built in, but this is basically standard. Though no simd support.

Full SIMD support thru gcc/clang vectorization
