URL: https://github.com/apache/doris/pull/65341

   ## Proposed changes
   
   Backport master PR #58137 to branch-4.1:
   
   - Remove unstable regression case 
`fault_injection_p0/test_inverted_index_cache.groovy`.
   - Register the BE UT `CacheCombinationMatrix`, which covers the 
query/searcher cache hit/miss matrix.
   - Keep branch-4.1's typed inverted-index reader test interface while 
resolving the cherry-pick conflict.
   
   ## Root cause
   
   The branch-4.1 x64 NonConcurrent case still runs an old debug-point 
regression test that master already removed in favor of BE UT coverage. The 
regression test can fail with an intentionally injected error when the runtime 
path reaches `InvertedIndexReader.handle_searcher_cache_miss`.
   
   Failing example:
   
   - Build: `201293`
   - Occurrence: `2000000108`
   - Test: 
`fault_injection_p0.test_inverted_index_cache.test_inverted_index_cache`
   - Error: `[INTERNAL_ERROR]handle searcher cache miss`
   
   ## Validation
   
   - Verified commit `86b9973e2bf` / PR #58137 was not in `origin/branch-4.1`.
   - Checked no duplicate open branch-4.1 PR for this case.
   - Resolved cherry-pick conflict by preserving branch-4.1's current typed 
query interface.
   - Ran `git diff --check origin/branch-4.1...HEAD`.
   
   Full BE UT was not run locally.
