Arpad Müller baf395983f Turn BlockLease associated type into an enum (#4982) ...

## Problem

The `BlockReader` trait is not ready to be asyncified, as associated
types are not supported by asyncification strategies like via the
`async_trait` macro, or via adopting enums.

## Summary of changes

Remove the `BlockLease` associated type from the `BlockReader` trait and
turn it into an enum instead, bearing the same name. The enum has two
variants, one of which is gated by `#[cfg(test)]`. Therefore, outside of
test settings, the enum has zero overhead over just having the
`PageReadGuard`. Using the enum allows us to impl `BlockReader` without
needing the page cache.
