feat: Pass starting replication value from Tap to Target

### Feature scope Taps (catalog, state, tests, etc.) ### Description I would like Targets to have access to the `starting_replication_value` that is set in a Stream when incremental. The primary use case is to allow the target to perform different actions depending on that value. I believe this to be a relatively common flow used in the world of extract-load processes so it would be beneficial to have as a core feature. One example: a SQL based Target being able to see that the starting_replication_value is None (i.e. first time run or full-refresh) and truncating the target table. The existing solutions of `hard_delete` does not meet this need because: 1. If messy data was synced and the source was cleaned up, `hard_delete` would not cleanout those dirty records in the target; and 2. single record deletions are prohibitively expensive in OLAP databases. ## Potential solution Update this method to write a state message immediately after writing the starting replication value: https://github.com/meltano/sdk/blob/bad876d539da483ada658685878c2b94e003d54d/singer_sdk/streams/_state.py#L121-L169 ``` def write_starting_replication_value( ... write_starting_replication_value(state, value) self._is_state_flushed = False self._write_state_message() ``` The target `_process_state_message()` could then read it in by parsing it out of the STATE message: ``` { "type": "STATE", "value": { "bookmarks": { "EXAMPLE-STREAM": { "replication_key": "last_update_date", "replication_key_value": "2024-09-26T09:04:54 AD", "starting_replication_value": "2024-09-26T09:04:54 AD" } } } } ```
