  1. Fix unintended drop of active replication origins 

    Currently, if two backends configure the same replication origin and one backend
resets it first, the acquired_by flag is cleared without recognizing the active
usage by the first backend. This can result in the unintended dropping of the
origin, potentially leading to issues if the shared memory of the dropped origin
is reused for a newly created origin. Such reuse could cause unpredictable
advancement of a different slot by the remaining backend holding the memory of
the dropped origin.

This commit addresses the issue by introducing a reference count for replication
origins. The count is incremented when a backend sets up the origin and
decremented upon a reset. As a result, the replication origin is only dropped
when the reference count reaches zero.
