Arpad Müller 6a906c68c9 Make {DeltaLayer,ImageLayer}::{load,load_inner} async (#4883) ...

## Problem

The functions `DeltaLayer::load_inner` and `ImageLayer::load_inner` are
calling `read_blk` internally, which we would like to turn into an async
fn.

## Summary of changes

We switch from `once_cell`'s `OnceCell` implementation to the one in
`tokio` in order to be able to call an async `get_or_try_init` function.

Builds on top of #4839, part of #4743
