This PR bumps Apache Arrow version from 10.0.0 to 11.0.0. Main changes related to PyAmber: ## Java/Scala side: - Distribute Apple M1 compatible JNI libraries via mavencentral ([#14472](apache/arrow#14472)). - Improve performance by short-circuiting null checks when comparing non null field types ([#15106](apache/arrow#15106)). - Extend Table copy functionality, and support returning copies of individual vectors ([#14389](apache/arrow#14389)). - Several enhancements to dictionary encoding ([#14891](apache/arrow#14891), ([#14902](apache/arrow#14902), ([#14874](apache/arrow#14874)). - Extend Table to support additional vector types ([#14573](apache/arrow#14573)). - Enhance and simplify handling of allocation management by integrating C Data into allocator hierarchy ([#14506](apache/arrow#14506)). ## Python side: - PyArrow now requires pandas >= 1.0 ([ARROW-18173](https://issues.apache.org/jira/browse/ARROW-18173)). - Added support for the [DataFrame Interchange Protocol](https://data-apis.org/dataframe-protocol/latest/purpose_and_scope.html) for pyarrow.Table ([GH-33346](apache/arrow#33346)). - Support for custom metadata of record batches in the IPC read and write APIs ([ARROW-16430](https://issues.apache.org/jira/browse/ARROW-16430)). - The Time32Scalar, Time64Scalar, Date32Scalar and Date64Scalar classes got a .value attribute to access the underlying integer value, similar to the other date-time related scalars ([ARROW-18264](https://issues.apache.org/jira/browse/ARROW-18264)). - Casting to string is now supported for duration ([ARROW-15822](https://issues.apache.org/jira/browse/ARROW-15822)) and decimal ([ARROW-17458](https://issues.apache.org/jira/browse/ARROW-17458)) types, which also means those can now be written to CSV. ## Issues fixed: - Now Do_action (from Python server back to Java Client) is returning a stream of results properly, and it alerts when the results are not fully consumed by the client. Such results will be used to send the flow control credits back from the Python side. We limit the results to be exact 1 for now, although it can be a stream. - Fix a bug in the Python proxy server, when unregistered action is invoked, it should not parse and return the results.
