Optimize Named Locks by Removing __all_dbms_lock_allocated Persistence

[Mai-icy]

Task Description

Migrate oceanbase/oceanbase-lite!1089 to SeekDB.

The change removes persistence through __all_dbms_lock_allocated and keeps MySQL named-lock state in memory.

Solution Description

• Keep MySQL named locks in the in-memory named-lock manager.
• Update session cleanup and reset-connection handling.
• Expose named locks and their object names through the virtual object-lock view.
• Preserve named-lock cleanup errors.
• Remove obsolete named-lock inner-table helpers and storage inventory entries.

Passed Regressions

• git diff --check upstream/master...HEAD
• Full compilation and regression testing have not yet been run on the migrated branch.

The original MR updated mysqltest coverage. Five legacy mysqltest files no longer exist on the current GitHub master, so their changes were not reintroduced:

• tools/deploy/mysql_test/r/mysql/simple_ddl.result
• tools/deploy/mysql_test/test_suite/table_lock/r/mysql/lock_func_basic.result
• tools/deploy/mysql_test/test_suite/table_lock/t/lock_func_basic.test
• tools/deploy/mysql_test/test_suite/view/r/mysql/cdb_objects.ce.result
• tools/deploy/mysql_test/test_suite/view/r/mysql/cdb_objects.result

Updates to the two test-result files still present in SeekDB were migrated.

Upgrade Compatibility

This changes named-lock state from inner-table persistence to in-memory runtime state. Upgrade and restart behavior should be reviewed before merge.

Other Information

• Original GitLab MR: oceanbase/oceanbase-lite!1089
• Original source branch: task/2026072800117800650
• Original GitLab tip: 1d7f1b4bf05a287147da020de12049dfd249176f
• The seven original commits were transplanted in order onto the latest oceanbase/seekdb:master; authorship and commit messages were preserved.
• GitLab and GitHub use unrelated Git histories, so commit SHAs changed during migration.

Release Note

Manage MySQL named locks in memory, expose them through the virtual object-lock view, and remove obsolete __all_dbms_lock_allocated persistence helpers.

Three Major findings remain at the current PR head: connection reset can retain table locks, mixed named/table wait cycles escape deadlock detection, and the new test suite is not wired into a runnable target.
