Merge pull request #18064 from stonea/improve_lookForBadRTCalls_errorMsg
Improve lookForBadRTCalls error message.
Specifically by suggesting alternatives when lookForBadRTCalls finds memory
allocation functions like malloc or free.
So now instead of getting a message like this:
Error: found call to "malloc"
We should get:
Error: found call to "malloc" consider using "chpl_mem_alloc" instead
