The [FROM_HEX_BINARY](https://docs.snowflake.com/en/sql-reference/functions/hex_decode_binary) frunction is equivalent to the `Unhex` function that is already supported by sqlglot. To support it, we just had to add the map in snowflake and add the transform in duckdb. Partially solves tobymao#4852, we still need to add support for `FROM_HEX_STRING`.

The HEX_DECODE_BINARY function is equivalent to the
Unhexfunction that is already supported by sqlglot. To support it, we just had to add the map in snowflake and add the transform in duckdb.Partially solves #4852, we still need to add support for
HEX_DECODE_STRING.Testing:
Duckdb (playground)
Bigquery
(Note that Bigquery outputs binary data (bytes) in base64)
Snowflake
(Note that Snowflake outputs binary data in hex format)
