optimize binary size of RisingWave

[BugenZhao]

The binary for x64 Linux of the recent release (v1.6.1) is 206 MB after compression, or 302 MB including the Java connector. Although RisingWave is primarily designed to be a server software where the binary size may not be critical, optimizing the binary size can enhance the experiences for users who use RisingWave in a lightweight manner.

As a contrast, here's a list of the compressed binary sizes of some other databases:

• GreptimeDB, Rust, 61 MB
• Databend, Rust, 299 MB
• DuckDB, C++, 27 MB

Some portions that may contribute to the size:

• (undoubtedly) libraries for integrating with external connectors
• monophorization of the generic code
• debug symbols section
