Add another platform exception type to OutOfProcMiddleware

[sophiatev]

Summary

What changed?

This PR adds another exception type (FunctionTimeoutAbortException) to our check for platform-level exceptions when invoking orchestrations, entities, and notably Activities.

Why is this change needed?

This exception is thrown when a worker restarts after another Function has reached its timeout. Currently, since result.Succeeded is false in this case, we will fail the Activity even though it itself did not exceed the Function timeout. This PR changes the behavior to instead throw a SessionAbortedException, such that the Activity (or orchestration, entity, etc.) is retried.

Pull request overview

This PR fixes issue #2939 where activities (and orchestrations/entities) were being incorrectly marked as failed when a FunctionTimeoutAbortException was thrown due to another function's timeout causing a worker restart. The fix ensures this exception type is treated as a platform-level exception, triggering a SessionAbortedException for durable retry instead of a permanent failure.

Changes:

• Added FunctionTimeoutAbortException to the IsPlatformLevelException check (used by the orchestrator path) and added explicit checks in the entity and activity paths
• Added dedicated unit tests for entity and activity paths with FunctionTimeoutAbortException
• Added FunctionTimeoutAbortException to the PlatformLevelExceptions test data for orchestrator tests, plus minor code style cleanups (collection expressions, primary constructors, explicit types)

Pull request overview

This PR adds handling for FunctionTimeoutAbortException in the OutOfProcMiddleware to fix an issue where activities (and entities) would be permanently failed when another function on the same worker hit a timeout, causing a worker restart. The fix ensures these work items are retried (via SessionAbortedException) instead of being marked as failed.

Changes:

• Added FunctionTimeoutAbortException checks in the entity and activity execution paths of OutOfProcMiddleware, and added it to the IsPlatformLevelException method (used by the orchestrator path).
• Bumped Microsoft.Azure.WebJobs package version from 3.0.39 to 3.0.45 to gain access to the FunctionTimeoutAbortException type.
• Added unit tests for the new exception handling in entity and activity paths, plus added the exception to the existing orchestrator platform-level exception test data.

This PR fixes an issue (#2939) where activities (and entities) would permanently fail instead of being retried when FunctionTimeoutAbortException is thrown — an exception that occurs when another function on the same worker exceeds its timeout, causing a worker restart. The fix adds FunctionTimeoutAbortException to the set of recognized platform-level exceptions, ensuring the affected work items are retried via SessionAbortedException.

Changes:

• Added FunctionTimeoutAbortException checks to the entity and activity execution paths in OutOfProcMiddleware, and to the IsPlatformLevelException helper (which covers orchestrators).
• Bumped Microsoft.Azure.WebJobs from 3.0.39 to 3.0.45 to gain access to the FunctionTimeoutAbortException type.
• Added unit tests for the new exception handling in entity and activity paths, and added FunctionTimeoutAbortException to the existing orchestrator platform-level exception test data.
