DXIL validation should run ComputeViewIdState pass

[jenatali]

The serialized view ID state in the DXIL module is not validated against the rest of the contents of the module. Tools that produce DXIL (like the Mesa DXIL writer) can just not emit a view ID metadata node, even though they're using view ID, and validation will succeed. This also includes the input -> output dependency mapping data, which can just be omitted entirely without affecting validation.

If drivers need this data, it should be validated as part of the validator.
