Revise regression tests when legacy codec handling is enabled

Summary

Currently, automated tests are not executed for legacy codec handling. Over the time, some newly added tests are not compatible with the legacy codec handling. There are two ways to overcome this, either the tests should be revised or they should be excluded. The following tests are identified as not compatible:

• templateOctetstr
• oop
• defaultAlternative
• negativeTest (RT2)
• compileonly/Bug550623
• compileonly/ModuleAttributeCheck
• EncodeDecode/JSON/JsonComplexTest
• EncodeDecode/RAW/issue574
• XML/XmlWorkflow
• XML/EXER-whitepaper
