Support for RDB analysis reports

[artikell]

The PR add analysis capabilities to the valkey-check-rdb tool. Now the tool can statistically analyze various types of keys, expired keys, and key elements.

• Added the --profiler parameter to the valkey-check-rdb tool's rdb analysis functionality, which enables opening reports.
• Supported the --format parameter with two options, info and from, to provide more flexible output formats.

The content format is as follows：
