crypto: x86/chacha20 - Support partial lengths in 8-block AVX2 variant Add a length argument to the eight block function for AVX2, so the block function may XOR only a partial length of eight blocks. To avoid unnecessary operations, we integrate XORing of the first four blocks in the final lane interleaving; this also avoids some work in the partial lengths path.
