The analyzer already has a class with the same name, but a slightly
different purpose. (The analyzer's class represents a single message
associated with a source location, whereas the CFE's class represents
a message along with related context messages).
I'm currently embarking on an arc of work that I hope will eventually
culminate in unifying the analyzer and CFE diagnostic message
representations into a single set of classes. Until that unification
is complete, both representations will have to co-exist in the
`_fe_analyzer_shared` package. To reduce confusion during that time
period, I would like the classes to have distinct names.
Since the analyzer's `DiagnosticMessage` class is exposed through the
analyzer public API, analyzer clients may depend on the name. So it
makes sense to rename the CFE's `DiagnosticMessage` class.
Tested: standard trybots
