Fix calling stored procs on Postgres, and enable some tests

[rdicroce]

Fixes calling stored procedures on Postgres. Without this change, EclipseLink does SELECT * FROM name_of_proc which causes an exception. This change also removes the isJDBCExecuteCompliant() method, which is not needed anymore as far as I can tell, and enables a few stored procedure tests for Postgres to prevent regressions.

This PR targets the 4.0 branch but would also need to be done for 5.0.

It throws

[ERROR]   TestStoredProcedures.setup:54->createSimpleStoredProcedure:222 » Database 
Internal Exception: org.postgresql.util.PSQLException: ERROR: procedures cannot have OUT arguments

Apparently PG only supports OUT params since version 14. I have 17 installed, so it worked for me. I've modified the test to use INOUT instead for PG. It works on 17, and hopefully it works on whatever version you're testing with.

Thanks. Do you want me to make another PR for master branch? Or are you going to port it yourself?

[rfelcman]

Please make port to master.
Thank You

[rdicroce]

Will do. Do you want me to get rid of the isJDBCExecuteCompliant() method at the same time? Or just do a direct cherry-pick?

[rfelcman]

In master branch 5.0 it should be removed isJDBCExecuteCompliant(). There is possible do some EclipseLink API changes as this next major version is not released.
