MDEV-16329 [4/5] Refactor MYSQL_BIN_LOG: extract Event_log ancestor

Browse Source 
Event_log is supposed to be a basic logging class that can write events in
a single file.

MYSQL_BIN_LOG in comparison will have:
* rotation support
* index files
* purging
* gtid and transactional information handling.
* is dedicated for a general-purpose binlog
