Support full-text searching in Kvrocks Search

### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/kvrocks/issues) and found no similar issues.

### Motivation

This includes:
- Implementing full-text indexing algorithms, such as inverted index, etc.
- Implementing word tokenization algorithms, which may include languages other than English, such as Chinese.
- Adding full-text indexing support for KQIR Indexer.
- Implementing the executor for full-text indexing and adding support in IR optimizer.
- Supporting relevant syntax parsing in front-end languages (SQL, RediSearch query).

### Solution

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start by reading the referenced PISA, CLucene, and Redis full-text search materials, then locate the KQIR Indexer, IR optimizer, and SQL/RediSearch parsing entry points. Done would require coordinated indexing, tokenization, execution, optimization, and syntax support across these areas.
