[encoding/googlecloudlogentry] Add support for cloud armor logs

Is your feature request related to a problem? Please describe.

Currently, we do not have specific support for the JSON payload of Cloud Armor logs, and the whole Cloud Armor log is simply placed in the body of the log record.

The goal of this issue is to create a new struct for these logs, and unmarshal them using this struct. We can then follow the semantic conventions, since good performance is now ensured.

Describe the solution you'd like

There are no changes in the YAML configuration. The encoding extension will automatically detect the log based on the logName and then parse it correctly.
