*: Remove useless Macros/Graphite (#9805)

ref #6233

Remove useless `Macros`/`Graphite`

* Remove `Graphite` related codes. TiFlash only report metrics to `Prometheus`
  * Remove `MetricsTransmitter` that send metrics to `Graphite`
  * Remove `GraphiteWriter` in `BaseDaemon`
  * Remove `StorageSystemGraphite`
* Remove `Macros` that clickhouse use to substitute macro for `ReplicatedReplacingMergeTree`
  * Remove `StorageSystemMacros`
* Remove useless config `user_files_path`, `format_schema_path`
* Always use `profiles.default` as the setting prefix
