Create `RegularFileStateValueWithDigest` and `RegularFileStateValueWithContentsProxy` to replace `RegularFileStateValue` to reduce memory overhead.

The `digest` and `contentsProxy` fields are mutually exclusive in `RegularFileStateValue` class so we can refactor `RegularFileStateValue` into two classes, one of which stores `digest` and the other stores `contentsProxy`.
