## Which issue does this PR close?
<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases. You can
link an issue to this PR using the GitHub syntax. For example `Closes #123`
indicates that this PR will close issue #123.
-->
- Part of #27082.
## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.
For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->
The TopK fuzz tests use an unseeded RNG and cannot reproduc failure. Moves
them to the shared `FuzzTest` driver.
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here, but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
- Move `core/tests/fuzz_cases/limit_fuzz.rs` to `fuzz/tests/suites/limit.rs`.
- Case seed `k` selects the input size `SIZES[k % 4]` and the data seed `k /
4`. Each run has 4 cases, one for each size, as before.
- The data and the random limit come from the case seed. The run seed is
random, so each run still uses new data, and the driver prints the seed on
failure.
- `LimitFuzzer` and the `FUZZERS` table register the 4 suites. The suite
names are the old test names.
## What is the testing strategy for this PR?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
Briefly describe how this PR is tested, and point to the specific tests you
added. For example: 'This new feature is covered by the `sqllogictest` cases
added in `foo.slt`'.
If this PR does not add tests, explain why. For example, if the change is
already covered by existing tests, please mention it.
You should also check the `codecov` bot reply on this PR to confirm the
changed code is exercised.

I changed the TopK heap condition locally. `test_sort_topk_i32` failed with
`TopK mismatch` and printed the case seed.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
If there are any breaking changes to public APIs, please add the `api
change` label.

No
