[php-src] PR #24182: ext/sodium: revert addition of extendable output functions

Pull Request: https://github.com/php/php-src/pull/24182 Author: DanielEScherzer The extendable output functions treated the state as a string, rather than an opaque object, and only validated the lengths of the strings before converting them to the underlying libsodium objects. Thus, incorrect state values could be used to trigger out of bounds reads or updates. The following constants are removed: - SODIUM_CRYPTO_XOF_SHAKE128_BLOCKBYTES - SODIUM_CRYPTO_XOF_SHAKE128_STATEBYTES - SODIUM_CRYPTO_XOF_SHAKE256_BLOCKBYTES - SODIUM_CRYPTO_XOF_SHAKE256_STATEBYTES - SODIUM_CRYPTO_XOF_TURBOSHAKE128_BLOCKBYTES - SODIUM_CRYPTO_XOF_TURBOSHAKE128_STATEBYTES - SODIUM_CRYPTO_XOF_TURBOSHAKE256_BLOCKBYTES - SODIUM_CRYPTO_XOF_TURBOSHAKE256_STATEBYTES The following functions are removed: - sodium_crypto_xof_shake128() - sodium_crypto_xof_shake128_init() - sodium_crypto_xof_shake128_update() - sodium_crypto_xof_shake128_squeeze() - sodium_crypto_xof_shake256() - sodium_crypto_xof_shake256_init() - sodium_crypto_xof_shake256_update() - sodium_crypto_xof_shake256_squeeze() - sodium_crypto_xof_turboshake128() - sodium_crypto_xof_turboshake128_init() - sodium_crypto_xof_turboshake128_update() - sodium_crypto_xof_turboshake128_squeeze() - sodium_crypto_xof_turboshake256() - sodium_crypto_xof_turboshake256_init() - sodium_crypto_xof_turboshake256_update() - sodium_crypto_xof_turboshake256_squeeze()
