Add view CRUD event dispatching, hooks, audit mapping, and tests

[raushanprabhakar1]

What changes were proposed in this pull request?

• Introduce ViewInfo and view event types (pre/success/failure) for list, load, create, alter, and drop, aligned with existing OperationType view entries.
• Add ViewEventDispatcher to emit those events on the EventBus, and ViewHookDispatcher for ownership on create, privilege rename on view rename, and privilege cleanup on drop (mirroring table behavior).
• Wire GravitinoEnv so the view stack is ViewHookDispatcher → ViewEventDispatcher → ViewNormalizeDispatcher → ViewOperationDispatcher.
• Map the new events in AuditLog.Operation.fromEvent so audit logs are not UNKNOWN_OPERATION for view ops.
• Add TestViewEvent and extend TestOperation for audit mapping.

Why are the changes needed?

View operations did not go through the same listener and hook chain as tables, so EventListenerPlugin implementations could not observe view CRUD and audit could not classify view events. This addresses the subtask for table-style view event hooks.

Fix: #11002

Does this PR introduce any user-facing change?

Yes. Event listeners and audit integrations now receive view CRUD events (and related audit operation types). No REST or client API surface changes; viewExists remains without dedicated events, consistent with tableExists.

How was this patch tested?

• ./gradlew :core:spotlessApply :core:test --tests org.apache.gravitino.listener.api.event.TestViewEvent --tests org.apache.gravitino.audit.TestOperation -PskipITs

Pull request overview

This PR brings view CRUD operations in line with existing table behavior by adding an event + hook dispatch chain for views and ensuring audit log classification recognizes the new view events.

Changes:

• Added ViewInfo plus pre/success/failure view event types and a ViewEventDispatcher to emit them on the EventBus.
• Added ViewHookDispatcher to apply ownership and authorization-related hooks for view create/rename/drop.
• Wired the view dispatcher chain in GravitinoEnv and updated AuditLog.Operation.fromEvent + tests to cover audit mapping for view events.
