[TRAFODION-2294] Fix permissions hole in Explain
This set of changes does the following:
1. Changes EXPLAIN so that it does not cache the query plan of whatever
query it is explaining. This closes a permissions hole that otherwise allows
one to execute the query afterward without privilege checking.
2. Extract the SqlParser_Flags_Enum from parser/SqlParserGlobalsCmn.h into
a new file parser/SqlParserGlobalsEnum.h, to make it easier to use these
literals in executor code. I changed a few hard-coded constants to their
associated literals in executor/ExExeUtilExplain.cpp as well.
3. Update privs1/TEST120 regression test to include a test of the hole
fixed by item 1 above.
