<fix>[gpu]: add gpu normalized model schema

[ZStack-Robot]

Summary

• Backport the ZSTAC-75319 GPU spec normalization schema to 5.4.10 for ZSTAC-86476.
• Add GpuDeviceSpecVO.normalizedModelName column and index required by the premium dedup logic.

Root Cause

• GPU spec identity in the premium code path needs a normalized model key so same GPU models from different board vendors can be unified.

Verification

• ./runMavenProfile premium in registry.docker.zstack.io:80/pr-build-bin:2.41test-4 with zstack and premium mounted.

Resolves: ZSTAC-86476

该PR为数据库升级脚本，在GpuDeviceSpecVO表中新增normalizedModelName列（VARCHAR(255)，默认NULL），并创建对应索引idx_gpu_spec_normalized_model，用于支持按归一化型号名称查询。
