[REDO] Optimize Vector API slice and unslice operations

All the slice and unslice variants that take more than one argument can benefit from already intrinsic methods on similar lines as slice(origin) and unslice(origin).

Base Performance:
Benchmark (size) Mode Cnt Score Error Units
TestSlice.vectorSliceOrigin 1024 thrpt 5 11763.372 ± 254.580 ops/ms
TestSlice.vectorSliceOriginVector 1024 thrpt 5 599.286 ± 326.770 ops/ms
TestSlice.vectorSliceUnsliceOrigin 1024 thrpt 5 6627.601 ± 22.060 ops/ms
TestSlice.vectorSliceUnsliceOriginVector 1024 thrpt 5 401.858 ± 220.340 ops/ms
TestSlice.vectorSliceUnsliceOriginVectorPart 1024 thrpt 5 421.993 ± 231.703 ops/ms
