Adds ASIM AlertEvent normalization support for SentinelOne Singularity Alerts (ingested via CCF into SentinelOneAlerts_CL) by introducing new vim* and ASim* parsers, wiring them into the aggregate parsers, and shipping accompanying ARM templates + test artifacts.

Changes:

• Added new SentinelOne Singularity Alerts AlertEvent parsers (vimAlertEvent... and ASimAlertEvent...) with parameterized filtering + optional AdditionalFields packing.
• Registered the new parsers in imAlertEvent.yaml / ASimAlertEvent.yaml and updated corresponding ARM templates + full deployment template.
• Added schema/data validation test outputs and changelog entries for the new parser(s) and rollups.
