<!-- Thank you for submitting a pull request! We appreciate your time and effort. Please make sure to provide enough information so that we can review your pull request. The Summary and Testing sections below contain guidance on what to include. --> ## Summary <!-- If this PR is related to a tracked effort, please link to the relevant issue here (e.g., `Closes: #123`). Otherwise, feel free to ignore / delete this. In this section, please: 1. Explain the rationale for this change. 2. Summarize the changes included in this PR. A general rule of thumb is that larger PRs should have larger summaries. If there are a lot of changes, please help us review the code by explaining what was changed and why. If there is an issue or discussion attached, there is no need to duplicate all the details, but clarity is always preferred over brevity. --> Add Java Bindings for FixedSizeList Data Type. I am from the Apache Paimon community, and I aim to make Vortex a file format under the Paimon lake format. Currently, I want to integrate Paimon's VectorType with Vortex's FixedList, but JNI support is missing. Therefore, I am contributing this capability to the Vortex community. Closes: #4979 <!-- ## API Changes Uncomment this section if there are any user-facing changes. Consider whether the change affects users in one of the following ways: 1. Breaks public APIs in some way. 2. Changes the underlying behavior of one of the engine integrations. 3. Should some documentation be updated to reflect this change? If a public API is changed in a breaking manner, make sure to add the appropriate label. You can run `./scripts/public-api.sh` locally to see if there are any public API changes (and this also runs in our CI). --> ## Testing <!-- Please describe how this change was tested. Here are some common categories for testing in Vortex: 1. Verifying existing behavior is maintained. 2. Verifying new behavior and functionality works correctly. 3. Serialization compatibility (backwards and forwards) should be maintained or explicitly broken. --> 1. `DTypeTest.java`: For java JNI api. 2. `SparkTypesTest.java`: Fixed SizeList and Conversion from List to Spark Array Type 3. Manually validated in Apache Paimon integration: apache/paimon#7543 Signed-off-by: JingsongLi <[email protected]>

Purpose
See https://vortex.dev/
Vortex performs well in terms of vectors, and introducing it can significantly help us gain significant advantages in vector storage. (https://paimon.apache.org/docs/master/append-table/vector/)
