Convert History File from readline to replxx Format

Convert history file from readline format to replxx format. #25888 (Azat Khuzhin).
ClickHouse CLI history file format is converted from readline to replxx format.

Why it matters

This change upgrades the command line interface history handling by switching from the older readline format to the more modern replxx format, enhancing compatibility and feature support for command history in the ClickHouse client.

How to use it

Users will automatically start using the new history file format in the ClickHouse client without any additional configuration, as the conversion happens internally during client startup or history file loading.
