[FEATURE] Add SchemaTool CLI for DB Init/Validation/Info/Upgrade

### Describe the feature

Add SchemaTool, SchemaTool is designed to replace the traditional `source` script import method by providing a unified CLI that implements the following core features:

- Database Initialization: Automatically detect MySQL or PostgreSQL and execute the corresponding versioned initialization SQL.
- Integrity Validation: Compare the server version with the schema version and verify key tables and column definitions.
- Storage Inspection: Output current database connection details, warehouse path, and version status.
- Smooth Version Upgrades: Load and execute upgrade scripts sequentially based on the specified version range.

### Motivation

Currently, Gravitino’s initialization process depends on launching the MySQL client and running the source command to load SQL scripts. This approach has two main drawbacks:

- **Lack of elegance**: It requires manually entering the MySQL console, which is cumbersome and error‑prone.
- **No integrity checks**: After initialization, there is no automated verification of database objects, which can lead to inconsistencies between environments.

### Describe the solution

To address these issues, we need to design a new Schema tool (“SchemaTool”) that provides a standardized CLI for database initialization, integrity validation, storage inspection, and version upgrades.
