More reflection API features. (#4740)

* More reflection API features.

+ Lookup methods and members (by string) on types
+ Fix issue with looking up non-static members through the scope operator '::'
+ `GenericReflection`: Cast a decl to generic to access unspecialized generic parameter names and constraints
+ `GenericReflection`: Use `getGenericContainer()` from function, variable or type to access the 'nearest' generic parent along with specialization info
+ `GenericReflection::getConcreteType` and `GenericReflection::getConcreteIntVal`: to get the concrete type of a param in the context of the reflection object
+ `GenericReflection::getOuterGenericContainer` to go up one level and get the outer generic declarations (if there are more than one enclosing generic scopes)
+ `DeclReflection::getParent`: go to parent declaration.
+ Change `VariableReflection` to be a `DeclRef` rather than a decl (allows us to return properly substituted types for methods, members, and more)

* Fix Falcor issue
