feat(lambda): support for advanced logging (#28039)

Structured logging enables automated analysis of the logs, thus enables customers to perform quick exploratory and automated monitoring the health of their applications, and helps them troubleshoot their production issues faster. Structured logging is now considered to be a monitoring best practice.

Lambda is developing Advance Logging Controls to give developers and operators more control over their function logs. The feature allows customers to capture logs in JSON format and control the level of details in emitted logs. To ensure compatibility and enable these capabilities, four new fields (LogFormat, ApplicationLogLevel, SystemLogLevel, and LogGroup) will be added to the existing LoggingConfig structure. Also, even adding custom log group for Log group section to have the flexibility of changing the name instead of having it as default. This update empowers customers to define their logging behavior and efficiently manage their function logs, reflecting Lambda's commitment to delivering a user-friendly logging solution that addresses the evolving needs of users.
