Change the expression evaluation context from Unevaluated to ConstantEvaluated while...

Also address a typo from a prior patch that performed a similar fix during Parsing of default non-type template arguments.  I left the RAII ExpressionEvaluationContext variable Name as Unevaluated though we had switched the context to ConstantEvaluated.

There should be no functionality change here - since when expression evaluation context is popped off, for the most part these two contexts currently behave similarly in regards to lambda diagnostics and odr-use tracking.

Like its parsing counterpart, this patch presages the advent of constexpr lambda patches...
