Adds `runtime/shared.rs` which is imported by both `build.rs` and the rest of the crate, containing utilities used by both. Renames the `snapshot_from_snapshot` feature to `exclude_runtime_main_js` since that's what it does and it's relevant outside of snapshotting when `__runtime_js_sources` is specified.
