Add charset in logger based on Z/Os

[Sparsh Gupta (sp-gupta)]

Description

In INC-8143, customer is seeing unreadable logs in the z/os system as the logs are not translated to EBCDIC format.
Default charset in Java 21 is defined by JDK (defaulting to UTF-8).
In Java 8, it is defined by the OS (thus defaulting to IBM-1047 for Z/Os) and that's why previous CP versions didn't face this issue.

Added a config which appends the appropriate charset in the log4j2 configuration.
