CUDA version handling (#1301)

* render feature for CUDA compute model.

* Use SemanticVersion type.

* Enable CUDA wave tests that require CUDA SM 7.0.
Provide mechanism for DownstreamCompiler to specify version numbers.

* Enabled wave-equality.slang

* Make CUDA SM version major version not just a single digit.

* Fix assert.

* DownstreamCompiler::Version -> CapabilityVersion
