Add `const Border.uniform()` (#30640)

`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.
