[mlir] NFC - move declaration of `Range` to StaticValueUtils.h

`ViewLikeInterface.h` defines a struct `Range`, and it also depends on
`StaticValueUtils.h/cpp`. This change moves the definition of `Range` to
`StaticValueUtils.h`, which should not violate any existing dependency
requirement. This is done to support adding utilities using `Range`
under `Dialect/Utils` without creating a circular dependency on
`ViewLikeInterface`. It is possible that some targets depend on
`ViewLikeInterface` just for the `Range` struct. These can be later
updated to depend on the `MLIRDialectUtils` target.
