LPS-56674 fixes some Oracle-related issues. A full LPS-56674 backport is not feasible, so the goal is to make the minimal changes required in 6.2 to fix known ORA-00932 and ORA-00920 issues
Master is not affected as it was resolved with LPS-56674.
Oracle CI tests integration
Make sure all columns that we convert to CLOB in VerifyOracle.doVerify() get created properly in an empty database
Apply CAST_CLOB_TEXT to necessary columns in custom finders
Backport the the usage of CAST_CLOB_TEXT for the order by clauses to ee-6.2.x
When converting some column types in an Oracle database, errors ORA-00932 and ORA-00920 are thrown
