feat(snowflake): support properties before column definitions in CREATE statements

[eruditmorina]

Summary

Snowflake, in CREATE statements, accepts KEY = VALUE properties both after and before the column definitions, example:

CREATE TABLE t CHANGE_TRACKING=TRUE (id INT);
CREATE TABLE t (id INT) CHANGE_TRACKING=TRUE;

Both versions of the above example are valid, but currently passing parameters before column definitions fail to parse. This PR aims to fix this by overriding _parse_property_before to parse such properties.

As usual, happy to receive feedback and guidance to follow up.
