Revert Folly NestedRequestContextGuard

Summary:
This attempted to provide a deep copy guard for folly request context.

Per brainstorming (see task), we don't think that deep copying all metadata has legitimate use cases. And in fact, this has no usage in our codebase currently. Because it default to reset (when createChild is not overriden), the behaviour is also very confusing.

Guards's goal is usually to copy 1 metadata. The solution for that is to provide a shallow copy guard. Something that I will do on top of this revert.
I'll wait for both changes to be discussed and accepted before landing this one.

Fix set/unset for default folly RequestContext

Summary:
My guess is that if we allow to set data in the default context, we also expect set/unset to work.
It currently doesn't. This fixes it (at least, the test repro passes), but not sure it's the right fix.

Summary: [Folly] Cut non-`const` conversion overloads from `Range`, for both `operator T` and `to<T>`: let them be `const` member functions so that the converted-to object cannot update `Range` internal state.
