Abstract the FileChannel in the JournalChannel

### Motivation

Make the FileChannel in the JournalChannel can use different implement.
We found we can use [pmemstore](https://github.com/pmem/pcj)
as the JournalChannel read from. So abstract the FileChannel in the
JournnalChannel to make us can have a different implementation.

### Changes

- Add interface for supporting implement different FileChannel

This PR doesn't introduce any new things in the code. So make sure it can pass the CI
