InnoDB buffer pool resize messages are more succinct from this change:

Before:
```
2022-05-07 17:10:33 0 [Note] InnoDB: Completed resizing buffer pool from 14745600 to 19660800 bytes.
2022-05-07 17:10:33 0 [Note] InnoDB: Completed resizing buffer pool.
2022-05-07 17:10:33 8 [Note] InnoDB: Completed resizing buffer pool. (New size: 19660800 bytes).
```
After:
```
2022-05-07 17:10:33 0 [Note] InnoDB: Completed resizing buffer pool from 14745600 to 19660800 bytes.
```

Additionally, the INNODB_BUFFER_POOL_RESIZE_STATUS has more complete
info: it contains both the old and new buffer pool size values.
