feat(batch): add option to not throw `FullBatchFailureError` when the entire batch fails

[arnabrahman]

Summary

Currently, when using the Batch Processor utility, if all the records in a batch are marked as failed, the utility throws a FullBatchFailureError. However, there can be scenarios where we do not want to throw an error for this condition.

This PR adds a throwOnFullBatchFailure option, giving users the ability to bypass the FullBatchFailureError when the entire batch fails.

Changes

• Introduce throwOnFullBatchFailure option that can be passed as an option inside processPartialResponse or processPartialResponseSync functions
• During full batch failure
  • If throwOnFullBatchFailure is false, we will not throw FullBatchFailureError exception
  • If throwOnFullBatchFailure is not provided or is true, we will keep the current implementation of throwing FullBatchFailureError exception
• Update the relevant doc blocks
• Unit tests for full batch failure for processPartialResponseandprocessPartialResponseSync` function
• I believe we have to update the docs but couldn't figure it out in which section. For now, I have added a line for the option.

Issue number: #2122
