Rename methods to avoid ObjC KVC collisions. (#1699)

Note: Breaking API change on the Dictionary classes.

The numeric value classes were using "Value" in the naming, but this silently
collided with the KVC category on NSObject; meaning KVC code could break up a
keypath and call these selectors with the wrong types leading to crashes (even
though the code all would compile cleanly).

- Rename the methods to use the "type" instead of literal "Value".
- Update all the impls and tests.
- Enable the warning that will catch issues like this in the future.

+// Note on naming: for the classes holding numeric values, a more natural
+// naming of the method might be things like "-valueForKey:",
+// "-setValue:forKey:"; etc. But those selectors are also defined by Key Value
+// Coding (KVC) as categories on NSObject. So "overloading" the selectors with
+// other meanings can cause warnings (based on compiler settings), but more
+// importantly, some of those selector get called as KVC breaks up keypaths.
+// So if those selectors are used, using KVC will compile cleanly, but could
