URL: https://github.com/apache/doris/pull/69899
### What problem does this PR solve?
Issue Number: None
Related PR: #68795
Problem Summary:
Cherry-picked from #68795. A row policy with a user variable in `USING`
(e.g. `restaurant_id = @authorized_restaurant`) makes `SHOW ROW POLICY` fail
with `Invalid call to sql on unbound object`. The fix implements
`UnboundVariable#computeToSql`.
We ran into this issue in production on 4.1.3. We can't list our row
policies, which makes managing them pretty difficult. Hopefully we can get this
fix into the next 4.1 release.
`RowPolicyFilterSqlTest.java` changes are left out because that test does
not exist on branch-4.1.
### Release note
Fix `SHOW ROW POLICY` failing when a row policy's `USING` clause references
a user variable.
