Accelerate byte lookup in string with `bytealg/indexbyte`
`bytealg/indexbyte` will use AVX or SSE instruction set, if possible,
which could accelerate `CopyStringIn` function by 28%.
In worst case(CPU doesn't support SSE), `bytealg/indexbyte`
will degenerate to traversal lookup. When dealing with
short strings, `bytealg/indexbyte` has the same performance level as
before.
