[system] Add missing conditional checks to render preserve_original_event tag when toggled on

[devamanv]

Proposed commit message

The PR contains changes to make sure the preserve_original_event tag is rendered without having to add that manually. Complete details have been captured in the related issue. Affected datastreams are application, security, and system.

Checklist

• I have reviewed tips for building integrations and this pull request is aligned with them.
• I have verified that all data streams collect metrics or logs.
• I have added an entry to my package's changelog.yml file.
• I have verified that Kibana version constraints are current according to guidelines.

Author's Checklist

Following are some of the sanity checks that must be passed at all times:

no preserve_original_event and no tags ==> no tags are rendered
no preserve_original_event but tags ==> only tags should be rendered
preserve_original_event but no tags ==> only preserve_original_event is rendered under the tags section
preserve_original_event and tags ==> render all tags including preserve_original_event under the tags section 

How to test this PR locally

• Spin up the Elastic stack and point your elastic-package to the running Kibana instance
• Build the package locally and install the package using elastic-package install --zip system-1.54.1.zip
• Upgrade the integration to the latest version i.e. 1.54.1, there shouldn't be any errors. If you find any errors while upgrading, please report it by adding a comment to this PR.
• Add the integration to an agent policy and notice the tags sections application, security, and system datastream. The preserve_original_event should be rendered when toggled on, and all others tags should render if added in the advanced options at the time of adding the integration.
