readers/mutation_readers: compacting_reader: remember injected partition-end

Browse Source 
Currently injecting a partition-end doesn't update
`_last_uncompacted_kind`, which will allow for a subsequent
`next_partition()` call to trigger injecting a partition-end, leading to
an invalid mutation fragment stream (partition-end after partition-end).
Fix by changing `_last_uncompacted_kind` to `partition_end` when
injecting a partition-end, making subsequent injection attempts noop.

Fixes: #11608
