server, metrics: let server TSO handle duration including failed requests

[JmPotato]

What problem does this PR solve?

Issue Number: ref #8281.

What is changed and how does it work?

- Delete the 99.999% percentile data because it does not correspond with TiDB and is too tail-end, which can easily mislead.
- Emphasize PD server/client in the panel title.
- Add corresponding 90/99/99.9% percentile data on the client handle duration for easier comparison.
- The PD server TSO handle duration now includes the failed requests, directly reflecting TSO HA anomalies in the monitoring data.

Check List

Tests

• Unit test
• Integration test
• Mannual test

Release note

Let PD server TSO handle duration including failed requests.
