[FEATURE] Use XDBC `remarks` column to populate column comments

[aiguofer]

Is your feature request related to a problem? Please describe.
Some users go through the painstaking effort of documenting their columns in their source systems so that their users (or consumers) know what the column represents in downstream tools. Currently, this data does not get surfaced in Tableau for connectors built with the SDK even if both the data source and the JDBC/ODBC connection populate it.

Describe the solution you'd like
The standard way of passing this information in JDBC and ODBC is via the remarks column. It would be great if Tableau used this field to auto-populate the comments for each field if available.

Describe alternatives you've considered
We have considered providing the ability to generate the TDS files for download with available comments + hierarchies included, but there is lacking documentation on the structure and reverse engineering these seems brittle.
