Adds support for Oracle 23c database.
There are following changes

  • Oracle23Platform platform classes added
  • New Oracle JDBC driver 23.x.x.x has, in some cases, different behaviour for boolean type. There are changes in PL/SQL calls.
  • Fix when empty String ("") is inserted into table column like ...CLOBDATA CLOB NOT NULL... Solution is based on conversion into java.sql.Clob, because solution based on SimpleAppendCallCustomParameter("empty_clob()") and DatabasePlatform.appendParameter() leads into another test failures.
  • Fix for loss of precision if DB table is automatically created if entity using java.time.LocalDateTime, java.time.LocalTime.
  • JDBC Driver update

This PR is based on backports from #1876 and #1969.
