### What problem does this PR solve?
Issue Number: None
Related PR: #64285
Problem Summary:
`enable_segment_limit_pushdown` is the replacement switch for the old common
expr pushdown session variables that were removed as no-op FE variables. The
variable was already marked fuzzy, but fuzzy initialization still skipped
randomizing it because many regression cases explicitly pinned the old
variables.
This PR migrates regression cases that set `enable_common_expr_pushdown` or
`enable_common_expr_pushdown_for_inverted_index` to use
`enable_segment_limit_pushdown` instead, including both true and false
settings. Cases that had conflicting old settings in one `SET_VAR` are
normalized to a single `enable_segment_limit_pushdown` setting. After the case
cleanup, fuzzy mode now randomizes `enableSegmentLimitPushdown`.
### Release note
None
### Check List (For Author)
- Test: Manual test
- `git diff --check HEAD^ HEAD`

- `rg` verification that regression suites no longer reference the old
common expr pushdown variables outside data files
- `rg` verification that no regression hint has conflicting or duplicate
`enable_segment_limit_pushdown` settings
- Behavior changed: No
