branch-4.2: [fix](regression) Isolate eliminate_distinct_constant database
(#70105) (#70108)
### What problem does this PR solve?
Issue Number: N/A
Related PR: #70105
Problem Summary:
Backport #70105 to `branch-4.2`.
`eliminate_distinct_constant` and `eliminate_aggregate_constant` both
drop, create, and use `test_aggregate_constant`. When the regression
runner executes them concurrently, either suite can drop the database
while the other is inserting or querying, causing intermittent failures.
Give `eliminate_distinct_constant` its own database,
`test_distinct_constant`, by updating its three database setup
statements. The existing SQL assertions and expected results are
unchanged.
### Release note
None
### Check List (For Author)
- Test
- [ ] Regression test
- [ ] Unit Test
- [ ] Manual test (add detailed scripts or steps below)
- [x] No need to test or manual test. Explain why:
- [x] Other reason: This test-only change replaces three database
identifiers. Static checks confirmed that the new database name is
unique to this suite, the suites no longer share a database, and `git
diff --check` passes. Live regression execution was not performed.
- Behavior changed:
- [x] No. Product behavior is unchanged; this change isolates
regression-test data.
- [ ] Yes.
- Does this need documentation?
- [x] No.
- [ ] Yes.
### Check List (For Reviewer who merge this PR)
- [ ] Confirm the release note
- [ ] Confirm test cases
- [ ] Confirm document
- [ ] Add branch pick label
