Function aliases improve issues

[kkk25641463]

Snowflake to_geometry() function match with ST_GEOMETRYFROMWKB and ST_GEOMETRYFROMWKT.But in databend code, the register_aliases only depend on alias_name which will cause the registered functions to be overwritten.

    pub fn register_aliases(&mut self, fn_name: &str, aliases: &[&str]) {
        for alias in aliases {
            self.aliases.insert(alias.to_string(), fn_name.to_string());
        }
    }
    registry.register_aliases("st_geometryfromwkb", &[
        "to_geometry",
    ]);
    registry.register_aliases("st_geometryfromwkt", &[
        "to_geometry",
    ]);

Who have any plans for improvement?

can we detect the input is wkb or wkt in function execution?

Ok，I will implement it separately, not as an alias.
