hg-core: make `Index` owner of its bytes (D8958#inline-14994 followup 1/2)

Prevent building `Index` every time it is needed. It was a bad idea anyway.

When `Index::new` will return `Result` it will avoid things like `Revlog::len`
returning `Result<usize>` instead of `usize`.

[X] make `Index` owner of its bytes
[ ] make `Index::new` return an error if `offset != bytes.len()`
