Remove unnecessary OnBatchCompleteListener (#54685)

Summary:

This interface is no longer necessary.
It was used in legacy arch to communicate between `UIManagerModule` and `NativeModuleRegistry`
This interface was public so I'm marking this as breaking, but I was not able to find any usage in OSS for this interface.

Changelog:
[Android] [Removed] - Remove unnecessary `OnBatchCompleteListener` used in Legacy Architecture

Differential Revision: D87866148
