Cooperative Vectors Test Plan

[VladM1076]

I have created a HLK/ExecTest test plan for the Cooperative Vectors feature and I am starting to work on its implementation.

Since the spec is still in flux, I have based it on the latest I am aware of and will keep it up to date as spec changes.

TODO: Update naming once spec is finalized.

Thank you for getting this in! I'll probably not get a chance to review this properly until next week, but in the meantime would it be possible to add a link to this from the cooperative vector proposal document as well please?

I added it to the cooperative vector proposal document as requested.
However since this is the HLSL test plan, wouldn't it be more appropriate in the vector-matrix operations proposal? Or just both?

The execution tests are really validating how the driver responds to the DXIL it receives. It's just that we write the tests in HLSL so we can use the compiler to generate the DXIL. That's much more convenient than hand-crafting DXIL!

Added more details on testing different shader stages in section 2.5.
Enumerated shader stages that need testing and explicitly called out helper pixel tests.

Added OOB tests to the plan and also updated InterlockedAdd to VectorAccumulate to align with new naming.
