[CI] Update job dependency and move dpsk v3.2 tests to 8-gpu suite

[Fridge003]

Motivation

• Add 2-gpu need for gb200 test, so gb200 ci test will not overrun
• Deprecate 8-gpu-deepseekv32 test suite, since it now has the same dependency as normal 8-gpu tests
• Move test_deepseekv32_backend to nightly suite since it covers unimportant use cases

Modifications

Checklist

• Format your code according to the Format code with pre-commit.
