Addition of SQL_ALIAS property to Dimension/Measure

**Is your feature request related to a problem? Please describe.**
Columns with long identifiers that work in Postgres do not work in cube - cube has a feature SQL_ALIAS on the cube, which is great and can work to shorten the overall identifier, but Cube is combining the table and column identifier into one Alias, and if a column name is close to 63 chars, the query can still fail with the "You requested hidden member:" [error](https://github.com/cube-js/cube/blob/bfc0708502f78902e481608b4f83c2eee6182636/packages/cubejs-api-gateway/src/helpers/transformData.ts#L239)

**Describe the solution you'd like**
I'd like a sql_alias property on the column (dimension/measure) as well (or maybe a backend automated md5 aliasing) - this feature might be helpful elsewhere / for other dbs as well - not certain

**Describe alternatives you've considered**
Shortening column names! But... things are complicated
