[Segment Replication] Use engine codec and replica shard ReplicationCheckpoint for replication events

[dreamer-89]

Description

1. Use replica shards's ReplicationCheckpoint for replication events. This is a bug because RC is sent to primary which uses it to compare replica shard specific attributes.
2. Use codec defined in engine config instead of default codec. This will break for cases where primary shard is not on default Lucene codec (e.g. Lucene95, Lucene94 etc).
3. Driven from review comment: Removed ReplicationCheckpoint param from SegmentReplicationTarget ctor and SegmentReplicationTargetService.startReplication method.

The codecov violation is reported on code which changed due to refactor rather actual functionality test. Added unit tests for ForceSegmentSync handler to increase the coverage.

The backport to 2.7 failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.7 2.7
# Navigate to the new working tree
pushd ../.worktrees/backport-2.7
# Create a new branch
git switch --create backport/backport-7732-to-2.7
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 adf7e2cdfbc13013448bc07ddac0fe09c07fd7e5
# Push it to GitHub
git push --set-upstream origin backport/backport-7732-to-2.7
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.7

Then, create a pull request where the base branch is 2.7 and the compare/head branch is backport/backport-7732-to-2.7.
