`Border.all()` is a factory constructor and thus not const
constructible. This change adds a `const Border.uniform()`
constructor and makes `Border.all()` delegate to it. This allows
callers to more likely be able to make their widget tree const
constructible.

When submitting data to a server, callers need a callback that will
get invoked after all the individual form fields are saved. If they
have a button that submits the form, they could just do this logic
in the click handler for the button (save the form, then submit to
the server), but if they have more ways than one to submit the form
(i.e. hitting enter while in a text form field), then it becomes
more convoluted and calls for a unified callback that will get
notified when the form is submitted.

None of its callers were using the return value, so no need to
invoke the `isValid` getter unnecessarily.

To describe what its return value represents

-* Inserted an `IconTheme` widget under `CupertinoTheme` to provide a default icon color when using `CupertinoTheme`.
* Changed `CupertinoTheme` to a `StatelessWidget`, to match the implementation of `Theme`
* Changed the nesting order of `Theme`'s sub widgets, to let `Theme.iconTheme` take precedence, so that `Theme`'s behavior is kept as is.
