[core][python][spark] Optimize data evolution write column metadata

[JingsongLi]

Purpose

Reduce DataFileMeta size for wide data-evolution tables with dedicated BLOB or vector fields.

This adds the disabled-by-default data-evolution.write-cols-optimization.enabled option. When enabled, normal files containing every non-dedicated field omit the redundant writeCols list, while dedicated files keep explicit columns.

Readers in Java and Python resolve omitted metadata from the historical table schema. The change also covers stats evolution, conflict detection and rewrite, streaming column discovery, global-index refresh, Daft reads, and Spark copy-files schema rebinding.

For compatibility, persist the option with CREATE TABLE or ALTER TABLE so file schema versions record the compact representation, and upgrade all readers before enabling it.

Reviewed the persisted CREATE/ALTER workflow across Java, PyPaimon, and Spark, including historical-schema resolution, BLOB/vector dedicated files, stats, conflict detection, compaction, streaming discovery, and copy-files schema rebinding. Targeted Python tests passed, and the targeted Java tests passed except for a local CodeGenerator service-discovery failure unrelated to this change. No blocking issue found.
