[fix/feature](kill) fix kill operation and support kill by trace id (#50791)
### What problem does this PR solve?
Related PR: #50776, #46882
Problem Summary:
1. Fix bug that `KILL connection_id` is not supported in Nereids
This PR #46882 implements `KILL` in Nereids, but it miss the grammar
`KILL connection_id` and treat it as `KILL query_id`. This PR fix it.
2. Unify the core code of `KILL` operation in both old and new planner
All core logic about `kill` are moved to `KillUtils` class. So that both
old and new planner and can have same logic.
3. Support Kill query by query id from all FE
Previously, when executing `kill query query_id;`, Doris will only find
query id in current FE. If not found, Doris will send the cancel request
to all Backends to try cancelling this query.
In this PR, I changed the logic. Doris will first find query id in
current FE, if not found, this `kill` command will be forwarded to all
other Frontends to then find it in other FEs. And Doris will no longer
send the cancel request to Backend.
4. Support Kill query by trace id from all FE
User can set a custom `trace id` by `set
session_context="trace_id:your_trace_id"`. And this trace id will be
bind to the subsequent queries in this connection. Then user can cancel
the query by trace id:
`KILL QUERY "trace_id"`
More details can be found in user doc:
