Improvement of ResultSet metadata

[prrvchr]

Description

These changes add the following to the metadata of a ResultSet:

• the catalog name (if not provided, the default value is an empty string)
• the schema name (if not provided, the default value is an empty string)
• the table name (if not provided, the default value is an empty string)
• the column label (if it exists, otherwise it's the column name)

They are intended to address issue #22306

Perhaps it would be a good idea to immediately add the missing information that will allow LibreOffice Base to efficiently update ResultSets, namely:

• ResultSetMetaData.isAutoIncrement(int column)

• ResultSetMetaData.isReadOnly(int column)

This will allow Base to recognize auto-incremented columns and allow me to know which ones have a calculated value.

Here's the latest complete version. I hope it passes the tests. Thanks in advance for your corrections.

I am not ready for this topic. Would prefer for that to be separate PR.

@findepi, Okay, I'm reverted and will propose a PR just for that.
