### What problem does this PR solve?
Issue Number: close #25867
Related PR: #xxx
Problem Summary: External table queries previously showed only coarse FE
metadata time in profile, making it hard to locate slow metadata access steps
for Hive, Iceberg, Hudi, and Paimon scans. This change records dedicated
profile timings for external partition value loading, partition metadata
loading, partition file listing, and file scan task planning. The scan nodes
keep a SummaryProfile reference so asynchronous split planning can also report
its metadata time.
### Release note
Expose more detailed FE external table metadata timing in query profile.
### Check List (For Author)
- Test: Unit Test
- Added SummaryProfile unit coverage for the new external table metadata
profile fields.
- `git diff --check` and `git diff --cached --check` passed.
- `./run-fe-ut.sh --run
org.apache.doris.common.profile.SummaryProfileTest` was attempted but could not
run because this environment only has JDK 11 and the FE test script requires
JDK 17.
- Behavior changed: Yes. Query profile now includes more detailed external
table metadata timing fields.
- Does this need documentation: No
