## Implement Connection ID-based Query Killing
### Key Changes:
- **Connection ID Management:**
- Added `connection_id` to `Session` and `QueryContext` in `src/session/src/lib.rs` and `src/session/src/context.rs`.
- Updated `MysqlInstanceShim` and `MysqlServer` to handle `connection_id` in `src/servers/src/mysql/handler.rs` and `src/servers/src/mysql/server.rs`.
- **KILL Statement Enhancements:**
- Introduced `Kill` enum to handle both `ProcessId` and `ConnectionId` in `src/sql/src/statements/kill.rs`.
- Updated `ParserContext` to parse `KILL QUERY <connection_id>` in `src/sql/src/parser.rs`.
- Modified `StatementExecutor` to support killing queries by `connection_id` in `src/operator/src/statement/kill.rs`.
- **Process Management:**
- Refactored `ProcessManager` to include `connection_id` in `src/catalog/src/process_manager.rs`.
- Added `kill_local_process` method for local query termination.
- **Testing:**
- Added tests for `KILL` statement parsing and execution in `src/sql/src/parser.rs`.
### Affected Files:
- `Cargo.lock`, `Cargo.toml`
- `src/catalog/src/process_manager.rs`
- `src/frontend/src/instance.rs`
- `src/frontend/src/stream_wrapper.rs`

### Enhance Process Management and Execution
- **`process_manager.rs`**: Added a new method `find_processes_by_connection_id` to filter processes by connection ID, improving process management capabilities.
- **`kill.rs`**: Refactored the process killing logic to utilize the new `find_processes_by_connection_id` method, streamlining the execution flow and reducing redundant checks.

## Commit Message
### Update Process ID Type and Refactor Code
- **Change Process ID Type**: Updated the process ID type from `u64` to `u32` across multiple files to optimize memory usage. Affected files include `process_manager.rs`, `lib.rs`, `database.rs`, `instance.rs`, `server.rs`, `stream_wrapper.rs`, `kill.rs`, `federated.rs`, `handler.rs`, `server.rs`,
`postgres.rs`, `mysql_server_test.rs`, `context.rs`, `lib.rs`, and `test_util.rs`.
- **Remove Connection ID**: Removed the `connection_id` field and related logic from `process_manager.rs`, `lib.rs`, `instance.rs`, `server.rs`, `stream_wrapper.rs`, `kill.rs`, `federated.rs`, `handler.rs`, `server.rs`, `postgres.rs`, `mysql_server_test.rs`, `context.rs`, `lib.rs`, and `test_util.rs` to
simplify the codebase.
- **Refactor Process Management**: Refactored process management logic to improve clarity and maintainability in `process_manager.rs`, `kill.rs`, and `handler.rs`.
- **Enhance MySQL Server Handling**: Improved MySQL server handling by integrating process management in `server.rs` and `mysql_server_test.rs`.

### Add Process Manager to Postgres Server
- **`src/frontend/src/server.rs`**: Updated server initialization to include `process_manager`.
- **`src/servers/src/postgres.rs`**: Modified `MakePostgresServerHandler` to accept `process_id` for session creation.
- **`src/servers/src/postgres/server.rs`**: Integrated `process_manager` into `PostgresServer` for generating `process_id` during connection handling.
- **`src/servers/tests/postgres/mod.rs`** and **`tests-integration/src/test_util.rs`**: Adjusted test server setup to accommodate optional `process_manager`.
