crypto: arm64/chacha20 - add XChaCha20 support Add an XChaCha20 implementation that is hooked up to the ARM64 NEON implementation of ChaCha20. This can be used by Adiantum. A NEON implementation of single-block HChaCha20 is also added so that XChaCha20 can use it rather than the generic implementation. This required refactoring the ChaCha20 permutation into its own function.
