riscv: Provide a vector only implementation of Chacha20 cipher

Although we have a Zvkb version of Chacha20, the Zvkb from the RISC-V
Vector Cryptography Bit-manipulation extension was ratified in late 2023
and does not come to the RVA23 Profile. Many CPUs in 2024 currently do not
support Zvkb but may have Vector and Bit-manipulation, which are already in
the RVA22 Profile. This commit provides a vector-only implementation that
replaced the vror with vsll+vsrl+vor and can provide enough speed for
Chacha20 for new CPUs this year.

Use scalar ALU and vector ALU together for chacha20 stream cipher

Fixes #24070

Use scalar ALU for 1 chacha block with rvv ALU simultaneously.
The tail elements(non-multiple of block length) will be handled by
the scalar logic.

Use rvv path if the input length > chacha_block_size.

And we have about 1.2x improvement comparing with the original code.
