gh-134696: align OpenSSL and HACL*-based hash functions constructors AC signatures (#134713)

OpenSSL and HACL*-based hash functions constructors now support both `data` and `string` parameters.
Previously these constructor functions inconsistently supported sometimes `data` and sometimes `string`,
while the documentation expected `data` to be given in all cases.
