GH-1037: Release ArrowBufs in VectorLoader on decompression failure

[Kaustav-Sarkar]

Summary

• Fix resource leak in VectorLoader when buffer decompression fails mid-loop
• Wrap decompression and loadFieldBuffers in try-finally to ensure all already-decompressed ArrowBufs are released on failure

Test plan

• Existing TestVectorLoader tests pass
• Verified decompressed buffers are released when a subsequent decompression throws
