[improvement](fe) Add virtual compute group switch metric #63036 - #64385

Problem Summary: Add an FE cloud metric that records virtual compute group active-standby switch events. The metric key uses virtual/src/dst compute group ids so a compute group rename updates the exposed labels without leaving stale old-name series.
Prometheus output example:
```text
doris_fe_virtual_compute_group_switch_total{virtual_compute_group_id="id1",virtual_compute_group_name="v_group_1",src_compute_group_id="id2",src_compute_group_name="p_group_1",dst_compute_group_id="id3",dst_compute_group_name="p_group_2"} 1
```
The metric value is the accumulated switch count for the labeled virtual compute group switch path.
Add FE metric doris_fe_virtual_compute_group_switch_total for virtual compute group active-standby switches.
- Test:
- Unit Test: bash run-fe-ut.sh --run org.apache.doris.cloud.system.CloudSystemInfoServiceTest
- Unit Test: bash run-fe-ut.sh --run org.apache.doris.metric.MetricsTest
- Manual test: git diff --check
- FE checkstyle: bash -lc "export DORIS_HOME=$PWD && source env.sh && cd fe && ${MVN_CMD} -pl fe-core -DskipTests checkstyle:check"
- Behavior changed: Yes. Add a new FE metric for virtual compute group active-standby switches.
- Does this need documentation: Nohello-stephen
