For avoiding confusion between API of `nsRange` and `StaticRange`, I'd like to rename `nsRange::CreateRange()` to `nsRange::Create()` because `StaticRange::CreateStaticRange()` is too long name and `StaticRange::CreateRange()` sounds odd. This patch renames it and changes related methods to template methods to avoid runtime cost of temporary `RawRangeBoundary` instance creation.
